The photoelectrochemical (PEC) water decomposition is a promising method to produce hydrogen from water. To improve the water decomposition efficiency of the PEC process, it is necessary to inhibit the generation of H 2 O 2 byproducts and reduce the overpotential required by cheap catalysts and a high current density. Studies have shown that coating the electrode with chiral molecules or chiral films can increase the hydrogen production and reduce the generation of H 2 O 2 byproducts. This is interpreted as the result of a chiral induced spin selectivity (CISS) effect, which induces a spin correlation between the electrons that are transferred to the anode. Here, we report the adsorption of chiral molecules onto titanium disulfide nanosheets. Firstly, titanium disulfide nanosheets were synthesized via thermal injection and then dispersed through ultrasonic crushing. This strategy combines the CISS with the plasma effect caused by the narrow bandgap of two-dimensional sulfur compounds to promote the PEC water decomposition with a high current density.

Front cover image: Despite remarkable progress has been made, the showstoppers of the Zin‐air batteries (ZABs) are still limited due to unsatisfied activity of the electrocatalysts for oxygen reduction reaction (ORR). In article number: https://doi.org/10.1002/cey2.192, Tian et al. design and fabricate the 1D PtFe hollow nanochains nanostructure (PtFe‐HNC) catalyst via a facile one‐pot method, which exhibits robust ORR activity, and the assembled ZAB with the prepared PtFe‐HNC/C as air cathode achieves a high peak power density and long‐term stability.

Ethanol Oxidation Reaction In article number 2203506, Xinlong Tian and co‐workers prepare 2D ternary Pd3Pt1Rh0.1 nanorings with efficient ethanol oxidation reaction performance via a facile one‐pot solvothermal approach, and systematic studies are carried out to reveal the mechanisms of the enhanced performance and C–C bond selectivity. The density functional theory calculations show that the introduction of Rh significantly enhances the C–C bond cleavage ability of the catalyst.
