Summary: In this study, silk fibroin sponges with nanopores were prepared and compared with silk fibroin sponges without nanopores. The results showed that the sponge with nanopores had higher porosity, water permeability, and cell attachment and proliferation. In a rat skin wound model, the nanoporous sponge accelerated wound healing, supported vascularization, collagen deposition, and increased epidermal thickness. Therefore, dressing materials with a hierarchical multiscale pore structure could independently promote cell migration, vascularization, and tissue regeneration, without the need for additional growth factors, offering a new strategy for designing better-performing wound dressings.

Summary: This investigation aims to tailor surface oxygen vacancies and active surface oxygen in MnO2 catalysts by doping copper, and achieve total catalytic oxidation of various VOCs. The results show that low-level Cu doping leads to the formation of tunnel-structured cryptomelane-type MnO2 with strong bulk oxygen mobility, exhibiting the best catalytic performance for toluene oxidation. Higher Cu loading results in Cu-doped layered birnessite-type MnO2 materials with rich oxygen vacancies and high active surface oxygen species, promoting the oxidation of isopropanol and formaldehyde, respectively. Oxygen vacancies and surface oxygen species play a crucial role in promoting the total oxidation of VOCs.

Summary: The electroreduction of CO2 to fuels is a viable method for renewable energy sources. This study investigates various catalyst design strategies, such as electronic metal-support interaction, to improve catalytic selectivity. A solvent-free synthesis method is used to prepare a copper-based metal-organic framework (MOF) that undergoes in situ decomposition/redeposition processes upon CO2 reduction, forming interfaces between Cu nanoparticles and amorphous carbon supports. This Cu/C catalyst shows high selectivity and stability in producing CH4, with a Faradaic efficiency of approximately 55% at -1.4 V versus reversible hydrogen electrode (RHE) for 12.5 h. Density functional theory calculation demonstrates the importance of interfacial sites between Cu and amorphous carbon support in stabilizing key intermediates for CO2 reduction to CH4. Adsorption of COOH* and CHO* at the Cu/C interface is significantly stronger than on Cu(111), promoting CH4 formation. Therefore, regulating electronic metal-support interaction can improve the selectivity and stability of catalysts for electrochemical CO2 reduction.

Summary: Antibiotic resistance is a major health issue and the diffusion of antibiotic pollution in the environment contributes to it. This review discusses the use of MXene and nano-zero-valent iron-based materials as effective methods to remove tetracyclines from wastewater. These materials can serve as adsorbents, photocatalysts, electrocatalysts, and membranes for the removal of tetracyclines. Importantly, a MXene derived from carbide nitride and bismuth oxobromide removed 99% of tetracycline in just 30 minutes, and a nano-zero-valent iron doped with graphene oxide and copper resulted in 100% degradation of tetacycline in 15 minutes.

Summary: Hydrogen (H2) is a potential energy carrier and feedstock for decarbonization, transportation, and chemical sectors, with the potential to reduce the effects of global warming. The current leading method for H2 production is steam methane reforming (SMR), although there is still room for improvement in terms of process intensification, energy optimization, and environmental concerns. Reactors using metallic membranes (MRs) can address these issues by operating at lower pressures and temperatures, resulting in potentially lower costs. Furthermore, metallic membranes, particularly Pd and its alloys, enable the production of highly pure H2 streams. This article discusses various methods of H2 production based on different energy sources, such as SMR with CO2 capture and storage (CCUS), methane pyrolysis, and water electrolysis. The importance of green H2 generation as a future affordable alternative and the role of nanomaterials in H2 synthesis and storage are also highlighted.

Summary: This study successfully reported the S-scheme-based hydrothermal synthesis of Ag-CuBi2O4/CNTs/Bi2S3 layered composites. The photocatalytic activity of nanocomposites with varying weight percent of Bi2S3 for the degradation of methyl orange (MO) and methylene blue (MB) dyes in the visible range was examined. Among the candidates, Ag-CuBi2O4/CNTs/Bi2S3 with a 10% loading of Bi2S3 showed the highest photocatalytic activity. The enhanced performance was attributed to the high surface area, reduced recombination rate of charge carriers, faster separation of photogenerated carriers, and high redox ability. The carbon nanotubes (CNTs) acted as a transfer bridge in the layered structure for electrons. The study provides an economical approach for obtaining a stable semiconductor-based photocatalytic system.
