The electrochemical reduction of N to NH (NRR) is challenging due to the lack of efficient catalysts under mild conditions. We constructed a series of 3d-transition-metal (3d-TM)-embedded asymmetric 2D MXene HMoCF with one H or F vacancy (H or F) based on first-principles calculation. Due to the strong steric effect of the surface-covered H or F terminals, N is favored to be adsorbed on H or F through the end-on mode rather than the side-on mode.

This study aimed to engineer Aspergillus usamii epoxide hydrolase (AuEH2) through a rational mutagenesis strategy to customize high enantioselectivity mutant for rac-oFSO.

Here we discover that HO synthesized via two-electron electrochemical oxygen reduction (2e ORR) on the electrode surface can be efficiently and durably consumed to produce high-purity MO in an alkaline environment. The crucial factor lies in the in-time detachment of in situ-generated MO from the self-cleaning electrode, where the solid products spontaneously detach from the electrode to solve the block issue.

The discovery of efficient and stable electrocatalysts for the oxygen evolution reaction (OER) in acidic conditions is crucial for the commercialization of proton-exchange membrane water electrolyzers. In this work, we propose a Sr(OH)-assisted method to fabricate a (200) facet highly exposed strontium-doped IrO catalyst to provide available adjacent iridium sites with lower Ir-O covalency. This design facilitates direct O-O coupling during the acidic water oxidation process, thereby circumventing the high energy barrier associated with the generation of *OOH intermediates.
