Summary: Coupling graphene-based materials with SiC nanostructures is an effective strategy for improving photocatalytic CO2 reduction performance. In this study, vertical graphene (VG) sheets were synthesized on SiC nanowires derived from rice husks to form the VG@SiC/C composite. The resulting composite exhibited enhanced photocatalytic CO2 reduction, yielding CO and CH4 with yields of 25.5 and 2.3 μmol g-1 h-1, respectively, which is the highest CO yield among SiC-based photocatalysts. Defective VG sheets promoted sunlight absorption, CO2 adsorption and activation, electron-hole pair separation, and overall photocatalyst activity, leading to high CO2 reduction yield and selectivity.

Summary: Selective conversion of CO2 to CO with high Faradaic efficiencies (>99%) on planar silver electrodes was achieved using simple pyridinium-based additives, which form organic films altering CO2RR selectivity. Electrochemical kinetic and mechanistic data suggest that a hydrophobic organic layer inhibits hydrogen production selectively by limiting proton mass transport, while pointing to proton transfer as the rate-determining step instead of electron transfer for planar Ag electrodes.

Summary: Photocatalytic conversion of CO2 to CO using H2O as the electron donor is achieved for the first time using an Mg-doped SrTiO3 photocatalyst (Mg-SrTiO3) under monochromatic UV-light irradiation at 365 nm. The enhanced conversion of CO2 to CO is observed in the presence of an Ag-Co cocatalyst on Mg-SrTiO3, with a selectivity of over 99% towards CO evolution and a quantum efficiency of 0.05%. The morphology of Mg-SrTiO3, with edge-shaved cubic particles, influences the anisotropic distribution of photogenerated electrons and holes and enhances the photocatalytic activity.

Summary: In this study, a novel adsorbent, Co-Al-LDH@Hf/Ti-MCP-AS, was synthesized for selective CO2 adsorption and separation. The maximum CO2 adsorption capacity of Co-Al-LDH@Hf/Ti-MCP-AS was 2.57 mmol g(-1) at 25 degrees C and 0.1 MPa. The adsorption behavior followed the pseudo-second-order kinetics and Freundlich isotherm models, and the adsorption occurred through acid-base interactions between amine functional groups and CO2.

Summary: In this study, a SrCO3/SrTiO3 catalyst was prepared via in-situ synthesis of SrCO3 on the surface of SrTiO3 nanosheets by the hydrothermal method. The catalyst exhibited high selectivity and activity in photocatalytic CO2-to-CO reduction, with a production rate of 23.82 μmol g(-1) h(-1). The distinguished performance and selectivity were attributed to the adsorption energy of CO, surface oxygen vacancies, and the heterojunction structure of SCO/STO, which enhanced charge separation and improved photocatalytic activities.

Summary: In order to achieve commercial CO2 electrochemical reduction to C2+ alcohols, the selectivity and production rate need to be further improved. This study presents a room-temperature one-step synthetic strategy to fabricate a highly stable Cu aerogel as an efficient CO2 reduction electrocatalyst. The Cu aerogel obtained by reducing Cu2+ using a weak reductant showed a high selectivity for C2+ products, while the Cu aerogel prepared using a strong reductant was favorable to generating CO.

Summary: CuGa catalyst promotes efficient electrocatalysis of CO2 to C2+ products at high current density through p-d orbital hybridization. The p-d hybridization of Cu and Ga enriches reactive sites, enhances the binding strength of the *CO intermediate, and facilitates C-C coupling. This strategy can be extended to other p-block metal-doped Cu catalysts to further enhance CO2 electroreduction for C2+ production. This is the first study to utilize p-d orbital hybridization interaction in a p block metal-doped Cu catalyst to promote electrochemical CO2 reduction to generate C2+ products.

The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

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.
