Summary: In order to alleviate the energy crisis and achieve the transformation of renewable energy sources, there is great interest in developing low-cost, highly efficient, and stable oxygen evolution reaction (OER) electrocatalysts for water splitting. A facile one-step solvothermal strategy was used to fabricate amorphous iron-cobalt-molybdenum oxide flakes containing MoSx and sulfate (FCMOS) which exhibited a low overpotential, lower Tafel slope, large electrochemical active surface area, and excellent durability. The excellent OER performance of FCMOS can be attributed to the acceleration of the *OH -> *O + *H reaction by MoSx, optimization of the deprotonation of *OOH by sulfate, and the synergistic polymetallic effect.

Summary: In this study, an effective strategy for improving the electrocatalytic CO2 reduction reaction (CO2RR) performance of a Zn foil electrode is reported. The oxide-derived and CTAB-modified Zn electrode (OD-Zn-CTAB) prepared by electrochemically reducing the air-annealed Zn foil electrode in the presence of CTAB exhibits high electrocatalytic activity and selectivity for CO production. The greatly enhanced CO2RR performance of OD-Zn-CTAB can be attributed to the increased number of active sites originating from the surface reconstruction and the formation of a favorable CTAB-modified electrode/electrolyte (E/E) interface that can efficiently adsorb and activate CO2 while inhibiting the competitive H-2 evolution reaction.

Summary: A highly defective, self-supported porous carbon membrane (HDPCM) electrode was developed by CO2-assisted thermal etching of carbonized wood. The as-fabricated HDPCM is heteroatom-free and exhibits abundant intrinsic carbon defects, resulting in enhanced CO2 adsorption and activation capability. It showed high efficiency for electrocatalytic CO2-to-CO conversion, with a FECO of 81.1% and a j(CO) of -3.88 mA cm(-2) at -0.66 V versus RHE. After hydrophobic treatment, the HDPCM could be directly used as an integrated gas-diffusion electrode (GDE) in the flow cell, achieving a much enhanced and relatively stable j(CO) (-50 mA cm(-2) at -0.76 V vs. RHE). This work not only provides an effective strategy for creating intrinsic defects on carbon-based electrocatalysts but also offers new insights into the development of integrated metal-free carbon-based GDEs for large-scale CO2 electroreduction.

Summary: This study demonstrates the ability to enhance the CO2RR on a Zn foil electrode by directly introducing cationic surfactants with long-alkaryl chains in the electrolyte. The addition of CTAB in the KHCO3 solution significantly improves the CO2RR efficiency, resulting in a higher CO Faradaic efficiency (FECO) and CO current density (j(CO)) compared to the Zn foil electrode without CTAB. The enhanced CO2RR efficiency is attributed to the dynamic adsorption of positively charged long-alkaryl chains on the polarized Zn foil electrode, which promotes the penetration and adsorption of CO2 while suppressing the competing HER. DFT calculations further reveal that the CTAB-modified E/E interface reduces the energy barrier of *CO desorption, enhancing the efficiency of CO2 reduction to CO.

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.
