Co-upcycling strategy enables cross-system conversion from LiB to Zn I 2 chemistry. • Upcycled battery exhibits high I 2 redox kinetics and dendrite-free Zn plating. • Anode-free design validates interfacial engineering of recycled electrode materials. With a growing amount of spent lithium-ion batteries estimated to accumulate over years, developing efficient recycling methodologies becomes urgent. Despite many efforts in this direction, the current routes require costly procedures with limited efficiencies and give rise to the under-utilization of recovered materials over both electrodes. Here, we put forward a co-upcycling strategy by integrating hydrometallurgy with Joule heating to address these concerns. Inspired by the Zn − iodine battery research community, we fully utilize the regenerated anode and cathode species from SLIBs into constructing prototype Zn − I 2 battery affording dual-electrode regulation. Operando spectroscopic characterizations and theoretical simulations reveal the co -upcycled materials simultaneously help mitigate polyiodide shuttle effect and ameliorate Zn deposition reversibility. Leveraging this strategy, the thus-derived anode-free Zn − I 2 pouch cell demonstrates an energy density of 229 Wh kg −1 . Techno-economic analysis further suggests the material usage and energy consumption in our protocol are notably low. This work is anticipated to establish an innovative paradigm of environmentally sustainable solutions toward next-generation energy storage. Integrated Joule heating and hydrometallurgical approach is developed to upcycle dual electrodes into anode-free zinc−iodine batteries. Temperature-mediated regulation endows the cobalt-limited catalysts with high cathode loading and shuttle inhibition affording, while graphite serves as functional anode. This work reduces raw material cost, energy consumption and improving the overall energy density. Download: Download high-res image (130KB) Download: Download full-size image

Biomass utilization coupled with CO 2 fixation offers a promising approach to produce sustainable carbon–neutral biofuels and chemicals while contributing to reducing CO 2 emissions. In this study, we proposed a method for synchronous bio-oil upgrading and CO 2 fixation by co-electrolysis in a sealed, undivided cell equipped with a metal cathode and a sacrificial anode. Results showed that the reactive components in bio-oil reacted with CO 2 during co-electrolysis, enhancing the abundance of the esters and formic acid by 57.2% and 270.2%, respectively. The CO 2 fixation rate was enhanced by 4.6% after co-electrolysis of bio-oil and CO 2 , with the control experiment in the absence of bio-oil. Additionally, the Cu cathode showed superior catalytic activation for upgrading bio-oil and achieving the highest CO 2 fixation, owing to its high selectivity for multi-electro transfer products. To summarize, the ketones and the phenolic derivatives in bio-oil could react with CO 2 to form organic esters and acids, while the 2–3 rings and heavy components in bio-oil tended to polymerize and generate insoluble products (polymers). Ultimately, we proposed a carbon-negative distributed biomass processing station system and discussed the future perspective on synchronous bio-oil upgrading and CO 2 fixation by co-electrolysis in this work.

Ceftriaxone sodium (CTX) is a typical β-lactam antibiotic in pharmaceutical wastewater. Although traditional biological treatments are low-cost and eco-friendly, antibiotics usually inhibit microorganisms , resulting in limited treatment performance. The biological co-metabolism process provides carbon sources and energy for microorganisms through co-substrate addition, thereby producing enzymes or cofactors to enhance the degradation of refractory pollutants. Therefore, the present study aimed to investigate the degradation performance of CTX through anaerobic biological co-metabolism. A simple co-metabolic substrate (i.e., glucose, 80 mg L −1 ) was added into an anaerobic-activated sludge system, and its mechanism was explored in terms of the variations in extracellular polymeric substances , microbial structure, and resistance genes. Additionally, the possible degradation pathways of CTX were described. The results showed that the degradation efficiency of CTX (200 mg L −1 ) was only about 35% within 8 h in the control group, while it increased to 67.6% in the experimental group with glucose. Chloroflexi , Actinobacteria , Bacteroidetes ADurb.Bin123, and Bacteroidales were the predominant bacterial species in the system. Additionally, the types of enzymes and the relative abundance of β-lactam resistance genes in the co-metabolic system significantly increased by 7 and 0.77%, respectively. Furthermore, nine primary anaerobic CTX biodegradation products were detected, indicating the existence of three possible degradation pathways. Overall, the study results provide a novel approach to treating CTX-containing wastewater.

Because of inefficient π-complexation of Cu+ sites, the CO solubilities of current available cuprous-based liquid absorbents are still unsatisfied and far away from equimolar CO capture. Herein, a novel cuprous-based quaternary deep eutectic solvent (DES) was prepared and employed as a superior absorbent for equimolar CO capture. It is found that the cuprous-based quaternary DES [Emim]Cl-CuCl-ZnCl2-EG showed a record CO uptake capacity (0.934 mol/mol, almost equimolar CO capture) and good ideal selectivities for CO/N2, CO/CO2, and CO/H2 at 1.0 bar and 298.2 K, which is by far the best liquid absorbent for efficient absorption of CO. The results of spectroscopic characterizations reveal that ZnCl2 and EG could weaken the Cu–Cl bond to have a significant red-shift, contributing to strengthen the Cu+ species interacting with more CO and thereby boosting CO capacity. Additionally, the CO absorption process was completely reversible, further demonstrating the good reusability of [Emim]Cl-CuCl-ZnCl2-EG. The cuprous-based quaternary DES thus shows good potential for efficient and selective absorption of CO.

In the tumor immunosuppressive microenvironment (TIME), antigen presenting cells (APCs) usually exhibit a tumor suppressor phenotype. Toll-like receptors (TLRs) agonists could reprogram M2-type macrophages to M1-type and stimulate dendritic cells (DCs) maturation. The combination of TLR7/8 and TLR9 agonists seems to have synergistic therapeutic efficacy. Here, we designed a lipid-coated mesoporous silica nanoparticle (MSNs@Lipo) for the co-delivery of TLR7/8 agonist resiquimod (R848) and TLR9 agonist CpG oligodeoxynucleotides (ODNs) (CpG@MSNs-R@L-M). R848 was firstly conjugated onto the nanoparticle via silane chemistry, which is acidic responsive drug release. Then, CpG was loaded onto the nanoparticle through the positive charge mainly from TLR7/8 agonist R848. Our in vitro experiments further indicated that both drugs have acid-responsive release properties and could be taken up by DCs and located on the endosomes of APCs. More importantly, CpG@MSNs-R@L-M could significantly improve the antitumor efficacy in B16F10 melanoma model. The mechanistic study demonstrated that CpG@MSNs-R@L-M could remarkably modulate the TIME by promoting the maturation of DCs and repolarizing macrophages from M2 to M1 phenotype and facilitating the infiltration of tumor cytotoxic T cells. It was concluded that in comparison to single agonist, the co-delivery of dual agonists, CpG and R848, can improve anti-tumor immune responses for cancer immunotherapy.

Nanothermometers that can reflect temperature in real-time are crucial for photothermal therapy. Near-infrared (NIR) fluorescent probes that conform to Boltzmann distribution will play an important role if they have the above characteristics. Here, the LiLuF 4 : Nd 3+ /Yb 3+ nanocrystals were designed and synthesized by control, exhibiting multiple bright near-infrared emission peaks at 925–1080 nm region at 280–360 K under the excitation of an 808 nm laser. The feasibility of being used as a nanothermometer was confirmed by testing the spectral variation with temperature and analysis.

Emulsified solid particles adsorbed at the oil–water interface can stabilise Pickering emulsions by acting as a physical barrier to the coalescence of oil droplets. Cellulose nanofibres (CNFs) have been used in food-grade Pickering emulsions because of their excellent performance as a low cost and sustainable material. Nicotinamide mononucleotide (NMN) is a small-molecule zwitterion with polar functionality capable of interacting with the CNFs. The ability of cationic CNFs and NMN to co-stabilise sunflower oil Pickering emulsions was investigated under various conditions using methods such as contact angle measurement, creaming stability, rheology, microscopy, thermal stability, and water-holding capacity. Emulsions with ultra-high stability, good gelation, and high plasticity were obtained using single-step shear dispersion with 0.25 wt% CNFs, 0.05–0.3 wt% NMN, and near-neutral pH. NMN stabilised the oil–water interface through electrostatic interactions and hydrogen bonding with CNFs. NMN transferred into the aqueous phase and interacted with CNFs to form a complex with a three-dimensional network structure, which improved the bulk viscosity and steric hindrance of the emulsion and created more compact adsorption of CNFs at the oil–water interfaces. Overall, the synergistic effects of various factors allow NMN to effectively co-stabilise Pickering emulsions with CNFs, making it an exciting method that can be used to encapsulate oil-soluble substances.

A new strategy has been proposed for synthesizing Co@CoO core–shell nanoparticles with a core–shell structure, which involves a facile solvent-thermal process in deep eutectic solvents (DESs). In contrast to the irregular sheet-like packing material obtained in water, twinned and 3D-ellipsoid-shaped nanoparticles were achieved in choline chloride (ChCl)/glycerol and ChCl/PEG-300, respectively. It was found that the nanoparticles were featured as metal Co(0) cores homogeneously wrapped by CoO shells after reduction under a H2 atmosphere. The Co@CoO core–shell nanoparticles showed good activity and stability for the hydroformylation of olefins, and the conversion of 1-octene can reach 99% at 130 °C under 4 MPa (CO/H2 = 1) pressure, and the selectivity to C9 aldehydes was reached up to 97%. The characterization by XPS, H2-TPR and HRTEM indicated that metal Co(0) species could be an active site for hydroformylation of olefins. Notably, the leaching of cobalt carbonyl species was highly dependent on the surface molar ratio of Co2+/Co0 as revealed by XPS spectra, and the surface CoO layer played an important role in suppressing the loss of active Co species in hydroformylation of olefins. Moreover, the core–shell nano-catalysts are easily separated magnetically from the reaction mixture and showed good recyclability in nine consecutive catalytic runs.

Twelve schiff base metal complexes were synthesized, and selected to adsorption desulfurization of dibenzothiophene(DBT). The result showed that the schiff base metal complex of melamine and cobalt (SF-S/Co) was the optimal adsorbent. Then SF-S/Co was characterized by scanning electron microscopy(SEM), Brunner − Emmet − Teller(BET) measurements, fourier transform infrared spectroscopy(FTIR), X-ray diffraction, and energy spectroscopy analysis. The effects of adsorbent amount and adsorption time on adsorption desulfurization were studied. The optimal adsorption condition was 1.5 g adsorbent/100 mL model oil, and the adsorption time was 8 min at room temperature. Under the optimal condition, the adsorption removal rate of DBT is up to 95%. The maximum adsorption capacity of the adsorbent for DBT is 21.66 mg/g. The adsorption capacity of adsorbent didn’t decreased obviously after being reused for 5 times. The adsorption isothermal model and dynamics of the adsorption process was further studied. The results show that the adsorption process of DBT by this adsorbent followed the Freundlich adsorption isothermal model and the pseudo-second-order model kinetics. The absorption effect of this adsorbent on different sulfides also was investigated. The order of removal efficiency was: dibenzothiophene > benzothiophene > thiophene.

La 0.8 Sr 0.2 MnO 3 (LSM) catalyst has been successfully prepared by solid phase method (G-LSM-T), sol–gel method (C-LSM-T) and molten salt method (S-LSM-T), using as-prepared MnCO 3 microspheres as templates, respectively. It was shown that the S-LSM-550 catalyst presented well-formed perovskite structures, large specific surface area (49.65m 2 /g) and promising catalytic activity in CO oxidation, which T 50 and T 90 for CO conversion over fresh S-LSM-550 were 145.14 °C and 170.73 °C. The S-LSM-550 calcined at 550 °C for 2 h exhibited excellent thermal stability and catalytic activity compared with the samples prepared by solid phase method and sol–gel method. Its superior catalytic performance could be greatly attributed to its stable microstructure, high surface Mn 4+ /Mn 3+ molar ratio and more available surface adsorbed oxygen species.

KBaPO 4 :Eu 2+ /Sm 3+ phosphor was synthesized via the high-temperature solid-phase reaction method. The structural properties, surface morphology, and optical properties of the synthesized samples were obtained by the X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and fluorescence measurements. The XRD patterns indicate that the crystal structure of KBaPO 4 has not been changed by co-doped with two rare-earth ions. Under the excitation of 400 nm, the Eu 2+ and Sm 3+ co-doped KBaPO 4 phosphors showed typical emission peaks at 430 (blue), 562 (yellow), and 600 nm (red). Meanwhile, with the increase of the Sm 3+ content, the photoluminescent (PL) emission intensity of Sm 3+ increased until the content reaches 0.12. However, the PL intensity of Eu 2+ ions gradually decreased, which indicated that there was a possible energy transfer between the two ions. Therefore, the obtained results indicated that Eu 2+ /Sm 3+ co-doped KBaPO 4 is a promising phosphor for the use in white light-emitting diodes with near ultraviolet chips.

Four types of Pt/C catalysts were synthesized by depositing platinum on various carbon materials, including graphene, graphitic carbon nitride, activated carbon, and carbon nanotubes. The microscopic structure and physicochemical properties of these catalysts were analyzed using different techniques such as TEM, XRD, BET, TGA, and XPS. The results indicated that platinum predominantly existed in the form of nanoparticles on graphene, graphitic carbon nitride, and carbon nanotubes. The performance of the catalysts in catalyzing CO oxidation was evaluated, and Pt/CNTs exhibited the highest efficiency compared to other catalysts. At a temperature of 170 °C, the conversion efficiency of CO on Pt/CNTs reached 96.5%. In situ DRIFTS experiments were performed, which did not show any peaks of CO adsorption on the surface of Pt/CNTs. Therefore, the oxidation of CO on Pt/CNTs was presumed to proceed via the Eley–Rideal (ER) mechanism. O2 was adsorbed and activated on Pt NPs to form a Pt NP–O–O*–CO structure with CO, which then decomposed to yield CO2 and an activated oxygen species (O*). Finally, O* reacted with CO again to produce CO2, completing the catalytic cycle.
