Summary: A rapid, cheap and feasible new approach using tetramethylammonium hydroxide (TMAH) as a nontraditional hydrolysis agent was successfully applied to synthesize Mg0.375Fe0.375Al0.25-LDH through mechano-chemical and co-precipitation methods. This method has advantages in terms of fewer steps, lower energy involvement, and elimination of alkaline cation contamination. The basicity of the catalysts was found to have a linear dependence on their catalytic activity in Claisen-Schmidt condensation, and the presence of these catalysts inhibited the oxidation of benzaldehyde.

Summary: In this study, a model of reversible redox-switching metal-organic framework single-unit-cell sheets is designed, where abundant metal single sites enable highly selective CO2 reduction, and reversible redox-switching metal sites effectively activate CO2 molecules. Using synthetic Cu-MOF single-unit-cell sheets as an example, the reversible switching of Cu-II/Cu-I single sites is found to facilitate the transfer of photoexcited electrons to CO2 molecules, leading to efficient activation of CO2. As a result, Cu-MOF single-unit-cell sheets achieve near 100% selectivity for CO2 photoreduction to CO with a high rate, outperforming previously reported photocatalysts.

Summary: In this study, ceria nanocrystals with different morphologies and exposed crystal facets were used as supports to synthesize Pd/CeO2 catalysts. The crystal facet effect of ceria on the catalytic activity of Pd/CeO2 catalysts in the selective oxidation of benzyl alcohol was investigated. It was found that the Pd/CeO2 nanorod catalyst exhibited superior performance, resulting in a higher overall catalytic activity compared to Pd/CeO2 nano-octahedra and Pd/CeO2 nanocubes. This work provides insight into the crystal facet-performance relationship of CeO2 and catalyst support design strategy for other multistep reactions.

Summary: In this study, it is discovered that vanadium doping can effectively inhibit surface-state-mediated charge carrier trapping, leading to improved efficiency of photocatalytic solar energy utilization. The presence of shallow trap states induced by vanadium doping is attributed to this inhibition. These vanadium-doping-induced states can trap and release charge carriers, allowing for enhanced performance in photocatalytic molecular oxygen activation and selective aerobic oxidation of organic compounds. This work provides an effective method for suppressing surface-state-mediated charge carrier trapping in semiconductor-based photocatalysis.

Summary: In this paper, a novel Kundu-nonlinear Schrodinger equation is derived through a 2 x 2 matrix spectral problem, which can be used to describe phenomena in optical propagation. The determinant expression of generalized (n, N-n)-fold Darboux transformation for the Kundu-nonlinear Schrodinger equation is obtained by solving algebraic equations. Additionally, three different types of solutions are obtained through the generalized (n, N - n) -fold Darboux transformation, including soliton solutions, degenerate soliton solutions, and interaction solutions between solitons and degenerate solitons, categorized into elastic interaction and bound-state. The conditions for their generation are discussed, and the properties of these solutions are analyzed graphically.

Summary: In this study, a near-infrared light-active periodic plasmonic heterostructure composed of semimetallic Bi nanoparticles and Bi-3(Se n Te1-n )(2) ternary alloy nanowires was designed to extend the light absorption range and utilize the surface plasmon resonance (SPR) effect more efficiently. Compared to noble metals, metallic Bi can excite the SPR effect in the entire ultraviolet-to-NIR range. The periodic heterostructure can alleviate the localization of the SPR and improve the charge transfer and redox kinetics through the efficient utilization of local electromagnetic fields and photothermal heating. As a result, the photoanode achieves an incident photon-to-current conversion efficiency of 22% at 800nm and a photocurrent density of 13.8 mA/cm² at 0.85 V-RHE under visible light without any cocatalysts.
