Summary: We demonstrate a composite photocatalyst for nitric oxide conversion with a Cu-Fe alloy, graphitic carbon nitride (g-C3N4), and ZnIn2S4. The superior photocatalytic performance of 6.45-fold that of g-C3N4 was confirmed. The delay effect on charge recombination was observed through time-resolved photoluminescence, and heterojunction establishment was attributed to the hole-trapping ability of ZnIn2S4. The combined effects of the Cu-Fe alloy were confirmed by NO-specific adsorption and conversion experiments, and the active species involved were examined via electron spin resonance. Density functional theory calculations revealed the molecular mechanisms of photocatalytic conversion of NO to NO3-. Therefore, g-C3N4|ZnIn2S4|CuFe has potential for sustainable and efficient pollutant conversion.

Summary: In this study, the concentration and position of sulfur vacancies in ultrathin ZnIn2S4 nanosheets were successfully controlled to optimize the photo-driven lignin model reforming process, leading to excellent selectivity for hydrogen and chemical monomers. The proton migration pathway was modulated through sulfur vacancy engineering, achieving high concentrations of sulfur vacancies in the bulk and on the surface of ZnIn2S4. This provides new mechanistic insights into biomass photoreforming and elucidates the structure/chemistry-catalysis correlation of ZnIn2S4 photocatalysts, which are crucial for photocatalyst design and solar fuel production.

Summary: Gas induced activation strategy was used to reconstruct CuZnOx/mSi catalyst surface by pretreating it in various environments, revealing the formation of active Cu nanoparticles with H2 pretreatment and CuCx nanofibers with CO pretreatment under high temperature reaction environment. The H2-treated CuZnOx/mSi-H2 showed three times higher catalytic activity for methanol synthesis compared to the CO-treated CuZnOx/mSi-CO.

Summary: Membrane technology is widely used for O2/N2 separation in industries, and cobalt-based compounds are known for their affinity for O2, which improves O2/N2 selectivity. A study successfully developed PIM-1 mixed matrix membranes containing cobalt-based ionic liquid, resulting in higher O2/N2 selectivity and lower O2 permeability. The application of a magnetic field further enhanced the O2/N2 selectivity of the membranes. These findings highlight the potential of these membranes for air separation.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
