Photocatalysis-self-Fenton system, integrating photocatalysis with Fenton technology, emerge as promising approaches for environmental remediation. In this study, we introduced K, Na doped g-C 3 N 4 /FeOCl (DCN/FeOCl) catalyst, where amino groups on the DCN surface interacted with unsaturated Fe on FeOCl, forming Fe–N bonds and a Z-scheme heterojunction . The resulting DCN/FeOCl demonstrated efficient H 2 O 2 production and rapid tetracycline (TC) degradation under visible light. The Z-scheme heterojunction and nitrogen vacancy enhanced electron-hole pair separation and O 2 adsorption. Additionally, we proposed a mechanism for dual-channel photocatalytic H 2 O 2 production. This work presents a novel strategy for in-situ H 2 O 2 production and activation, facilitating water decontamination .

The experiments of the adsorption removal of CS 2 impurity from a mimetic coke oven gas were performed by using a series of Na-type zeolites as adsorbents. Combining with the diffusion & simulation calculations and several characterizations, it's found both the development degree and the diffusion ability of microporous systems significantly influence the adsorption performance of these Na-type zeolites on which the physical absorption was predominant for CS 2 molecules. Firstly, compared with NaZSM-5 or NaSAPO-34, the NaY with FAU-type framework exhibited a much higher breakthrough adsorption capacity, primarily due to its much higher microporous surface area & volume and larger-size channels, which ensured a broader adsorption space, a high-efficiency molecule-diffusion and a high adsorption utilization of micropores. Secondly, alkali-treatment introduced some mesopores into NaZSM-5 crystals but also resulted in a declined integrity of microporous structure, causing an obvious decline of adsorption performance. Thirdly, the nano-crystal NaZSM-5 or NaY exhibited a much higher breakthrough adsorption capacity than that of the corresponding micron-crystal zeolite, primarily attributed to both the increased microporous surface area & volume and the shortened micropore diffusion-path length of the former. In addition, a breakthrough adsorption capacity of up to 0.251 g/g was obtained in the first adsorption use of a nano-NaY-0.909 sample at 298 K, and it's 0.229 g/g in even the sixteenth time of operation (by then, total adsorption service hours were 80.58 h). Our work may provide an important reference for developing high-performance adsorbents for removing gaseous CS 2 impurity in coke oven gas.

In this study, biomass-derived carbon material obtained from Lyocell fibers was first utilized as a gas sensor. The impacts of varying pyrolytic carbonization temperatures and pregrinding treatments on the structure, surface morphology, elemental composition, and gas sensitivity of the samples were thoroughly examined. The CL-500 sensor can realize rapid detection of trimethylamine with a high response (12.79k%, 500 ppm) and high selectivity at room temperature; the response/recovery times are 10 s and 2 s, respectively, and the theoretical detection limit is 3.96 ppm. Moreover, after four months, the response of the CL-500 sensor to trimethylamine fluctuated by less than 9.7 % compared with that of the fresh sensor, indicating good stability. It also shows good recovery after seven consecutive response-recovery cycles. Additionally, the CL-500 sensor has promising applications in real-life fish freshness monitoring. Theoretical calculations indicate that the introduction of trace amounts of Na enhances the sensing performance of this sensor for target gases. This study serves as a guide for developing cost-effective, high-performance gas sensors, promoting the efficient and high-value utilization of biomass waste.

Rechargeable Na-CO 2 batteries are considered to be an effective way to address the energy crisis and greenhouse effect due to their dual functions of CO 2 fixation/utilization and energy storage. However, the insolubility and irreversibility of solid discharge products lead to poor discharge capacity and poor cycle performance. Herein, a novel strategy is proposed to enhance the electrochemical performance of hybrid Na-CO 2 batteries, using water-in-salt electrolyte (WiSE) to establish an optimal reaction environment, regulate the CO 2 reduction pathway, and ultimately convert the discharge product of the battery from Na 2 CO 3 to formic acid (HCOOH). This strategy effectively resolves the issue of poor reversibility, allowing the battery to exhibit excellent cycle performance (over 1200 cycles at 30 °C), especially under low-temperature conditions (2534 cycles at −20 °C). Furthermore, density functional theory (DFT) calculations and experiments indicate that by adjusting the relative concentration of H/O atoms at the electrolyte/catalyst interface, the CO 2 reduction pathway in the battery can be regulated, thus effectively enhancing CO 2 capture capability and consequently achieving an ultra-high discharge specific capacity of 148.1 mAh cm −2 . This work effectively promotes the practical application of hybrid Na-CO 2 batteries and shall provide a guidance for converting CO 2 into products with high-value-added chemicals.

Osteoporotic bone defects are challenging to repair due to imbalances in bone resorption and formation, coupled with insufficient vascularization. To address these issues, it develops a trifunctional hydrogel (SF-ZIF@NA) designed to selectively inhibit osteoclast activity and enhance vascularized bone regeneration. By enzymatically removing sialic acid, SF-ZIF@NA prevents precursor osteoclasts (pOCs) from fusing into bone-resorbing mature osteoclasts (mOCs), thereby preserving pOCs and their anabolic functions. Additionally, the hydrogel releases Zinc ion (Zn 2 ⁺) in response to acidic conditions, promoting osteogenesis and angiogenesis. In vitro results confirmed that SF-ZIF@NA impedes osteoclast fusion, enhances platelet-derived growth factor-BB (PDGF-BB secretion from pOCs, and activates the FAK (focal adhesion kinase) signaling pathway to stimulate vascularized bone formation. In osteoporotic bone defect models, SF-ZIF@NA accelerated bone repair with increased bone density and vascularization. These findings demonstrate that SF-ZIF@NA offers a targeted and multifunctional strategy for osteoporotic bone regeneration by concurrently modulating osteoclast activity and promoting angiogenesis.

The intrinsic structural lability and limited processability of inorganic halide perovskites heavily hamper their commercial applications. Herein, we develop a facile and scalable room-temperature (RT) water-based procedure for the synthesis of Na–Cu-codoped CsPbIxBr3–x-embedded Pb(OH)I (denoted as the Na–Cu–CsPbIxBr3–x@Pb(OH)I) composite to overcome the above-mentioned bottlenecks. Compared to Na doping, the codoping with Na and Cu leads to a slight shift of the photoluminescence (PL) peak position from ∼612 to 622 nm, increases the PL intensity by 32.5 times, and improves the PL quantum yield from 1% to 5%. Notably, the optimized Na–Cu–CsPbIxBr3–x@Pb(OH)I composite displays outstanding stability under various harsh environments such as soaking in RT water or hot water (up to 90 °C) and annealing at high temperature, which indicates that Pb(OH)I can act as an effective water-blocking and protective encapsulation layer. It is more interesting that the photoluminescence (PL) intensity of Na–Cu–CsPbIxBr3–x@Pb(OH)I can be significantly increased to 2.17 and 1.29 times after soaking the sample in RT water for 35 and 105 days, respectively, and 1.25 times even after immersing in hot water (90 °C) for 6 h, indicating an improved optical property. Meanwhile, the crystal structure and emission wavelength are maintained. The insight of this work is quite beneficial for designing highly stable inorganic perovskite-based nanomaterials for realization in light-emitting devices and other optoelectronic devices.

The instability of the interfacial structure during the synthesis of iron carbodiimide (FeNCN) leads to a decline in its electrochemical performance during cycling. By depositing FeF 3 particles on the surface of FeNCN, the in-situ transformation of this FeF 3 nanolayer into a FeF 2 nanolayer effectively utilizes the discharge product Fe 0 . This process constructs a mechanically stable sandwich-structured SEI film, thereby enhancing the stability of the FeNCN electrode interface. Consequently, the FeNCN electrode exhibits a capacity of 350.54 mAh g −1 after 2000 cycles at 2 A g −1 , with a capacity retention rate of 99.54 %. This strategy provides crucial theoretical and technical insights for regulating carbodiimide-based materials to achieve stable, long-cycle performance in electrode materials.

The Qaidam Basin has potassium- and calcium-rich oil field brine resources at high temperatures. Since the phase diagram is a powerful tool to guide the separation and purification of inorganic chemical engineering for the development of potassium resources in oil field brine, the quaternary oil field brine system (Na+, K+, Ca2+//Cl– -H2O) and its two subsystems ((Na+, Ca2+//Cl– -H2O) and (K+, Ca2+, //Cl– -H2O)) at 338.15 K were reported for the first time by the isothermal dissolution equilibrium method. The compositions of the equilibrium solid phases were analyzed and identified by combined chemical analyzing and X-ray diffraction. The quaternary system has four crystallized regions corresponding to NaCl, KCl, KCl·CaCl2, and CaCl2·2H2O at 338.15 K, and the incongruent double salt KCl·CaCl2 occurred at 338.15 K. The study facilitates the enrichment of thermodynamic data and exploits brine-based potassium resources.

The semiconductor industry’s rapid evolution necessitates ultra-high-purity N-methyl pyrrolidone (NMP) as an essential electronic-grade solvent. The development of an efficient coordination material to reduce trace metal ions, particularly Na and K metal ions, to below 1 ppb in NMP solution is a significant challenge. To address this, a novel coordination material, St-DVB-g-ACE, has been developed for the removal of Na and K metal ions from NMP. The material was synthesized by grafting 4′-aminobenzo-15-crown-5-ether onto a strong acid gel resin. The resulting St-DVB-g-ACE-3 exhibited excellent coordination performance for Na and K metal ions, with maximum Langmuir adsorption capacities reaching 20,000 μg/g and 33,333 μg/g, respectively. Of particular interest was the ability of St-DVB-g-ACE-3 to reduce all trace metal ions in industrial-grade NMP to below 1 ppb within a fixed bed column, achieving the stringent requirements for electronic-grade NMP at the G3 level. Additionally, the absorbent enhances the purity of NMP from 99.82 % to 99.84 %, indicating that the material is not dissolved and can exist stably in NMP. Its excellent recyclability and reproducibility make it highly practical for industrial use. Density functional theory (DFT) simulation, complemented by spectral analyses, revealed the interaction force and thermodynamic properties between Na and K metal ions and crown ether ring, and illustrated the interaction between anionic sulfonic group (−SO 3 − ) and metal ions. The prepared resin-grafted crown ether adsorbents are highly effective in the thorough removal of trace metal ions from NMP solution, offering a novel and effective method for the production of electronic-grade NMP.

Titanium oxide (TiO2) has attracted great interest as a promising anode material for lithium (Li) ion batteries (LIBs) and sodium (Na) ion batteries (SIBs). However, the key factors that dictate the Li-ion and Na-ion storage and transportation in TiO2 remain unclear. Herein, we report a facile hydrolysis route to crafting a variety of high tap-density TiO2 spheres with controllable size and hierarchical pores. The Li-ion and Na-ion storage properties based on these TiO2 spheres were systematically investigated. The pore distribution and the size of TiO2 spheres were found to exert profound influence on the Li-ion and Na-ion storage and transportation. The Li-ion storage and transportation in dense TiO2 spheres was dependent mainly upon the micropore distribution and volume and independent of the size of spheres. In contrast, the excellent Na-ion storage and transportation in TiO2 spheres was enabled by the loose structure with a large macroscopic pore volume and shortened Na-ion diffusion length. High tap-density TiO2 spheres (1.06 g cm−3) with superior Li-ion and Na-ion storage properties were produced, exhibiting a Li-ion storage specific capacity of 189 mA h g−1 at 1C and a high capacity retention of 88.1% after 100 cycles, and a Na-ion storage specific capacity of 184 mA h g−1 at 1C and capacity retention of 90.5% after 200 cycles. The ability to understand the critical factors controlling the Li-ion and Na-ion storage in high tap-density TiO2 spheres enables their implementation for practical applications in Li-ion and Na-ion batteries.

Metal sulfides, one kind of electrode material with very high theoretical capacity, have been widely studied for use in lithium and sodium ion batteries. However, there are some problems hindering their applications in electrodes, such as low conductivity and volume expansion. The MOF introduces metals with different coordination strengths into an existing MOF structure, which improves the performance of the electrode to a certain extent. In this paper, Fe/Zn bimetallic MOF rod-like superstructure was prepared based on Ostwald theory. Accompanied by sulfuration, the MOF was effectively combined with MoS2 and GO, and the objective materials Fe7S8-C/ZnS-C@MoS2/rGO composites were successfully prepared. The MOF material provides a good frame and an efficient electron transport path, while the robust rGO wall effectively inhibits the pulverization of materials during the lithium/sodium intercalation/escalation courses. This particular material exhibited excellent cycling and rate capability performance when used in Li/Na-ion batteries. When used in Li-batteries, the electrode material delivered a specific capacity of 1598.3 mA h g−1 at 0.1 A g−1 and remained at 1196.7 mA h g−1 even after about 100 cycles and further exhibited a specific capacity of 368.68 mA h g−1 at the current rate of 5 A g−1 even after 1000 cycles, respectively. As for sodium batteries, these electrode materials exhibited an initial reversible capacity of 1053.6 mA h g−1 at 0.1 A g−1 and the reversible capacity was still as high as 592.2 mA h g−1 after 200 cycles. It is perhaps that this composite material with its particular architecture and composition is greatly beneficial for electron transfer and Li/Na ion diffusion. In the repeated physicochemical/nutrifying process, the appropriate distance between adjacent MOFs is of great help in preventing volume changes and thus improving the electrochemical performance.

High-voltage and low-cost manganese-based P 2-type oxides show real promise as promising cathode for sodium-ion batteries (SIBs). But the P 2 − O2 phase transformation and Na + /vacancy ordering results in the inferior structural stability and Na + diffusion coefficient , which further leads to rapid decay of capacity and poor rate capability. Herein, in consideration of the synergetic effects of dual cationic doping, electrochemically inactive Li + and active Co 3+ codoping are proposed to solve the above issues. The novel two-step doping strategy, Co doping during synthesis of precursors via coprecipitation reaction followed by Li doping during solid-state reaction, are rationally developed. As anticipated, the Li/Co codoped P 2-type oxide exhibits the absence of P 2 − O2 phase transformation and Na + /vacancy disordering, which gives rise to an outstanding cycling stability (86.7% capacity retention within 100 cycles at 0.1C) and high-rate capability (reversible capacity of 109 mAh g −1 even at 10C). In addition, the full-cells composed of the codoped P 2-type positive and hard carbon negative show high energy-density, good lifespan and high-rate property. This proposed cationic codoping provides an effective and scalable tactics for modulating the structural properties of high-voltage P 2-type cathodes for advanced SIBs.
