Crystallography regulation of a zinc (Zn) metal substrate to expose more (002) textures holds great promise for stabilizing Zn anodes. However, significant challenges remain in directly constructing a single (002)-plane-textured Zn metal anode (S-(002)-Zn) and realizing a sustainable (002)-texture exposure in working batteries. Herein, we report an anion and cation coregulated nonepitaxial electrodeposition to fabricate S-(002)-Zn by introducing 1-ethyl-3-methylimidazolium iodide (EmimI) additives in low-cost ZnSO4 aqueous electrolyte (ZS). Mechanistic studies reveal that the cooperation of Emim+ and I– with oriented adsorption behaviors on Zn can synergistically boost the (100) plane growth, depress the (002) plane growth, and suppress H2 evolution, thus enabling compact S-(002)-Zn electrodeposition. Moreover, other similar organic iodides (e.g., dimethyl-imidazolium iodide and 1-propyl-3-methylimidazolium iodide) are applicable to this scalable electrodeposition. On the other hand, the as-designed ZS-EmimI electrolyte can be directly applied in working Zn batteries, thus effectively sustaining the smooth (002) texture of S-(002)-Zn and inhibiting HER during cycling. Consequently, the combination of single-(002)-texture and ZS-EmimI electrolyte endows the S-(002)-Zn anode with an ultralong lifespan over 10,100 h (>14 months) at 1 mAh cm–2 and superior deep-cycling stability under 88.0% utilization (25 mAh cm–2) over 500 h and assures the stable operation of full Zn batteries.

Zinc, an essential trace element, is involved in many important physiological processes. Cell responses to zinc stress show time-dependent effects besides concentration-dependence and tissue-specificity. Herein, we investigated the time-dependent differential expression of the proteome in A549 cells after administered with ZnSO 4 for both 9 and 24 h using 2DE. 123 differentially expressed protein spots were detected, most of which were up-regulated by Zn 2+ treatment. Interestingly, 49 proteins exhibited significant differential expression repeatedly during these two treatment periods, and moreover showed a conserved change with different ratios and four time-dependent expression patterns. Pattern 1 (up-regulated with rapid initial induction and subsequent repression) and pattern 4 (down-regulated with steady repression) were the predominant expression patterns. The abundances of the proteins in patterns 1 and 4 after 24 h of zinc treatment are always lower than that after 9 h, indicating that exogenous zinc reduced the expression of proteins in cells after 24 h or longer. Importantly, these findings could also reflect the central challenge in detecting zinc homeostasis proteins by 2DE or other high throughput analytical methods resulting from slight variation in protein expression after certain durations of exogenous zinc treatment and/or low inherent protein content in cells. These time-dependent proteome expression patterns were further validated by measuring dynamic changes in protein content in cells and in expression of two proteins using the Bradford method and western blotting, respectively. The time-dependent changes in total zinc and free Zn 2+ ion contents in cells were measured using ICP-MS and confocal microscopy, respectively. The kinetic process of zinc homeostasis regulated by muffling was further revealed. In addition, we identified 50 differentially expressed proteins which are predominantly involved in metabolic process, cellular process or developmental process, and function as binding, catalytic activity or structural molecule activity. This study further elucidates our understanding of dynamic nature of the cellular response to zinc stress and the mechanism of zinc homeostasis.

In aqueous zinc-ion batteries, the growth of dendrite, hydrogen evolution reaction, and corrosion on the Zn anode result in rapid performance degradation and poor cycling stability, which significantly impede their commercial application. Herein, a tea polyphenol-zinc ion complex (denoted as Tp-Zn) is used as an electrolyte additive to reshape the Zn 2+ solvation structure and guide uniform zinc deposition. Tp-Zn interacts with water molecules via hydrogen bonding of hydroxyl groups, weakening the Zn 2+ -H 2 O solvation sheath and suppressing water-related side reactions. Moreover, Tp-Zn induces preferential Zn deposition, contributing to homogeneous zinc deposition. As a result, the Zn//Zn symmetric cell assembled with Tp-Zn achieves an ultra-long cycle life of over 4000 h at 0.5 mA cm −2 and more than 1300 h at 2.0 mA cm −2 . The Zn//Cu asymmetric cell can maintain stable plating and stripping for more than 900 cycles at 1.0 mA cm −2 , and the Zn//NaVO full cell maintains high specific capacity during stable cycling. This green and non-toxic Tp-Zn additive effectively stabilizes the Zn anode interface and enhances cycling durability, providing a new reference for the exploration of the commercialization of ZIBs.

As mineral resources are developed and exploited, the proportion of low-grade zinc ore increases. The concentrations of F - exceeding the optimal range may pose a risk to zinc hydrometallurgy . In the present research, Al 2 O 3 -ZnO microspheres (AZO) characterized by a substantial specific surface area were synthesized through a hydrothermal-roasting technique and applied in industrial zinc sulphate fluoride removal. The optimal adsorption conditions for AZO and the underlying adsorption mechanism were investigated. The results indicated that the adsorption at 12 g·L -1 dosage, original pH=5.32 of the solution and 323 K for 75 min, when the fluoride concentration was reduced to below 50 mg·L -1 , the fluoride removal percentage reached 73.32 %, and the adsorption capacity was 8.55 mg·g -1 . Kinetic studies revealed that AZO exhibited surface inhomogeneity, functioning as a heterogeneous adsorbent, with the fluoride adsorption process being predominantly chemical in nature. The isotherm model suggested that the removal process was characterized by homogeneous adsorption of a monomolecular layer, with a theoretical maximum adsorption capacity of AZO estimated at 9.479 mg·g -1 . FT-IR and XPS analyses demonstrated that the defluorination process occurs through ion exchange between F - and -OH, as well as the formation of Zn/Al-F complexes. Consequently, AZO present a novel approach for developing an effective adsorbent for defluorination in industrial ZnSO 4 solutions.

The hydrophobic internal cavity and hydrophilic external surface of cyclodextrins (CDs) render promising electrochemical applications. Here, we report a comparative and mechanistic study on the use of CD molecules (α-, β-, and γ-CD) as electrolyte additives for rechargeable Zn batteries. The addition of α-CD in aqueous ZnSO4 solution reduces nucleation overpotential and activation energy of Zn plating and suppresses H2 generation. Computational, spectroscopic, and electrochemical studies reveal that α-CD preferentially adsorbs in parallel on the Zn surface via secondary hydroxyl groups, suppressing water-induced side reactions of hydrogen evolution and hydroxide sulfate formation. Additionally, the hydrophilic exterior surface of α-CD with intense electron density simultaneously facilitates Zn2+ deposition and alleviates Zn dendrite formation. A formulated 3 M ZnSO4 + 10 mM α-CD electrolyte enables homogenous Zn plating/stripping (average Coulombic efficiency ∼ 99.90%) at 1 mA cm–2 in Zn|Cu cells and a considerable capacity retention of 84.20% after 800 cycles in Zn|V2O5 full batteries. This study provides insight into the use of supramolecular macrocycles to modulate and enhance the interface stability and kinetics of metallic anodes for aqueous battery chemistry.

A ZnSO4 electrolyte solution with impurity salts such as MnSO4 and MgSO4 is often used in zinc hydrometallurgical processes over a wide temperature range. CaSO4·2H2O(s) scaling and fluorine corrosion are two encountered problems in the process. Understanding the CaF2(s) solubility behavior in MSO4 (M = Zn, Mn, Mg) aqueous solutions at various temperatures helps remove Ca2+ and F– ions from the solution. However, CaF2(s) solubility data, especially at temperatures >298 K, have not been published yet. In this work, CaF2(s) solubilities in the CaF2–CaSO4–MSO4–H2O (M = Zn, Mn, Mg) quaternary systems and its subsystems of the CaF2–MSO4–H2O (M = Zn, Mn, Mg) at 348.15 K and the CaF2–CaSO4–MSO4–H2O (M = Zn, Mg) quaternary systems and the CaF2–MgSO4–H2O ternary system at 298.15 K are systematically measured. The results show that the CaF2(s) solubility in the MSO4 (M = Zn, Mn, Mg) aqueous solution of a certain concentration at 348.15 K is considerably higher than that at 298.15 K. At 298.15 and 348.15 K, the salting-in effect of MSO4 (M = Zn, Mn, Mg) on CaF2(s) solubility is enhanced with the order ZnSO4 < MnSO4 < MgSO4. At both temperatures, CaF2(s) solubilities in CaSO4·2H2O(s)- or CaSO4(s)-saturated MSO4 (M = Zn, Mn, Mg) aqueous solutions are generally lower than those in pure MSO4 (M = Zn, Mn, Mg) aqueous solutions. Particularly, the salting-in effect of MgSO4 on CaF2 is so strong that CaF2(s) dissolves completely and is converted to CaSO4·2H2O(s) and MgF2(s) in a concentrated MgSO4 aqueous solution. Hence, this study indicates that high temperatures and high salt concentrations increase the CaF2(s) solubility, making the removal of Ca2+ and F– ions from the system challenging. Further, the existence of impurity salts MnSO4 and MgSO4 makes it more difficult.

A series of Zn salts were used as catalysts for the reaction of glycerol and urea to produce glycerol carbonate and it was found that ZnSO4showed the highest catalytic activity. Furthermore, the effects of reaction parameters on the glycerol conversion and glycerol carbonate yield were studied in detail. The results indicated that the glycerol conversion and glycerol carbonate yield were increased with the reaction temperature, reaction time, and catalyst amount while the optimal reaction conditions were 140 °C, 240 min, catalyst amount of 5 wt% (based on the glycerol weight), and urea-to-glycerol molar ratio of 1.1:1. During the reaction, the ZnSO4catalyst is transformed into Zn(NH3)2SO4at the initial stage of the reaction and then further transformed into Zn(C3H6O3). Zn(C3H6O3) and (NH4)2SO4may be the true active species for the activation of urea and glycerol, respectively. The reaction mechanism is proposed in this article. Based on the experimental results, a reaction kinetics model considering the change in volume of the reaction system was also established, and the model parameters were obtained by fitting the experimental data. The statistical results showed that the established kinetics model is accurate.Keywords:glycerol;urea;glycerol carbonate;zinc sulfate;reaction kinetics

The amorphous porous layered-Al 2 O 3 derived from aluminium fumarate metal-organic frameworks (AlFu MOFs) by roasting at 773 K under air has been applied to remove fluorine ions from industrial ZnSO 4 solution. The amorphous porous layered-Al 2 O 3 was characterized by XRD, SEM and BET. The adsorption experiments were conducted under different conditions, including adsorbent dosage, initial pH, adsorption temperature and adsorption time. And the process of removing fluorine ions is well fitted with the pseudo-second-order kinetic model and Langmuir isotherm model, which is studied by the adsorption kinetics and isotherms. The theoretical maximum adsorption capacity was 12.05 mg g −1 . Moreover, the adsorption mechanism of the amorphous porous layered-Al 2 O 3 was analyzed by SEM-EDS and FTIR. The results indicate that the adsorption process is affected by complexation and ion exchange between fluorine ions and amorphous porous layered-Al 2 O 3 . The regeneration of the amorphous porous layered-Al 2 O 3 shows that the adsorbent could be reused to reduce the production cost.

Rechargeable aqueous zinc/vanadium pentoxide (Zn/V2O5) battery chemistry has recently attracted a great attention due to its high safety, material abundance, cost effectiveness, and desirable energy density. However, the reaction mechanism of V2O5 in an aqueous electrolyte remains a topic of discussion, and the limited life span resulting from the active materials dissolution hinders the further development of the Zn/V2O5 battery. Here, we report a long-life aqueous Zn/V2O5 battery using a simply ball-milled V2O5 cathode, a concentrated aqueous ZnSO4 electrolyte, and a metallic Zn anode. Electrochemical, structural, and spectroscopic analyses reveal that the V2O5 electrode experiences a highly reversible proton (H+) and Zn2+ co-intercalation mechanism in aqueous media, which differs from the conventional cognition that Zn2+ ion as the only charge carrier inserts into the V2O5 host. The electrolyte-involved (dis)appearance of zinc sulfate hydroxide on the electrodes’ surface caused by H+ (de)intercalation has also been clarified. In addition, the optimized 3 M ZnSO4 electrolyte can not only suppress the dissolution of the V2O5 cathode but also enhance the stability of the Zn anode, thereby enabling the stable operation of the Zn/V2O5 battery with a reversible capacity of 357 mAh g–1 after 2000 cycles without obvious decay at 2.0 A g–1. This work opens up frontiers in the mechanism insight and electrolyte formulation for aqueous Zn batteries.

Long-term upward trend of international copper prices pushes up sphalerite flotation operational costs, making the development of copper-free collectors an urgent demand for efficient sphalerite recovery. In the present study, the potential of 2-ethylhexyl thioglycolate (ET) as a collector reagent for non-activated ZnSO 4 -depressed sphalerite and its adsorption mechanism are evaluated by micro-flotation tests, multiple characterizations and DFT simulations. Micro-flotation tests confirm that ET can efficiently recover non-activated depressed sphalerite under high-alkalinity conditions, demonstrating improved floatability compared with the SBX collector. Surface physicochemical analyses reveal that the surface composition of depressed sphalerite evolves from hydrophilic inorganic species to hydrophobic organic components after ET adsorption. Combined with XPS analysis and theoretical simulations, it is revealed that the strong adsorption affinity of ET toward depressed sphalerite stems from synergistic adsorption mechanism, in which sulfhydryl groups coordinate with surface Zn sites and ester oxygen forms hydrogen bonds with –OH groups to build stable adsorption configurations. This work establishes a molecular-scale screening and design strategy for high-efficiency collectors of non-activated depressed sphalerite based on specific chemical bonding and hydrogen bonding interactions, and provides theoretical insights into the development of collectors with multiple active sites.

Zinc-ion hybrid capacitors (ZIHCs) with high energy density is commercial need as energy storing devices, but facile preparation is still a challenge. Herein, we proposed a combined strategy for preparation of ZIHCs with high performance. For this purpose, a nanoemulsion assembly approach with Pluronic F127 as structure-directing agent, 1, 3, 5-trimethylbenzene as pore-expanding agent, polydopamine as carbon and nitrogen source, was used to synthesize hierarchically N-doped porous carbon spheres (N-HNCSs). The optimized sample of N-HNCS-1 exhibited uniform size of 150 nm, hierarchically porous structure, large surface area (705.46 m 2 g −1 ), and N-doping amount of 6.51 %. These properties were beneficial for the transportation of the electrolyte ions resulted in that the N-HNCS-1 electrode displayed superior electrochemical performance with specific capacity of 142 mAh g −1 . Furthermore, the Zn//ZnSO 4 + ZnI 2 //N-HNCS-1 ZIHCs achieves an exceptionally high energy density of 347.7 Wh kg −1 , which is 3-fold higher than that of Zn//ZnSO 4 //N-HNCS-1 ZIHCs. To elucidate this outstanding performance, we investigate the mechanisms involved, including Zn 2+ deposition/stripping, SO 4 2- /I - adsorption/desorption, Zn 4 SO 4 (OH) 6 ⋅0.5 H 2 O precipitation/dissolution, and redox reactions relating to iodine ions . The incorporation of ZnI 2 redox-electrolyte significantly enhanced the energy density by providing prominent pseudocapacitance via the faradaic reaction. Therefore, the high performance of Zn//ZnSO 4 + ZnI 2 //N-HNCS-1 ZIHCs is attributed to the introduction of nitrogen (N) species, advantageous 3D carbonaceous framework, and redox reactions triggered by adding zinc iodide (ZnI 2 ) into the aqueous zinc sulfate (ZnSO 4 ) electrolyte. This groundbreaking research opens up possibilities for the development of high-energy ZIHCs, and advancements in energy storage technology.

Low carrier mobility of WO 3 material limited its application and development in the field of optoelectronic devices , especially used in photodetectors. Herein, a quasi-solid-state photoelectrochemical photodetector based on WO 3 film and solid-state electrolyte (PVA/ZnSO 4 ) was constructed. The WO 3 film was prepared by a hydrothermal method . The obtained WO 3 /PVA/ZnSO 4 quasi-solid-state photoelectrochemical photodetector exhibits superior near ultraviolet light detection performance and better stability compared with the traditional WO 3 /ZnSO 4 photoelectrochemical detector. Considered the volatility of water in the electrolyte, a small amount of NaCl was added into the electrolyte to increase the water retention property of the electrolyte. The obtained results demonstrate that NaCl has some water retention property and can improve the stability of the device effectively. These obtained results provide the data foundation for the research and development of photodetectors based on WO 3 materials.
