Ultrafine Nanoporous Ordered High-Entropy Intermetallics with Isolated Multisites toward Electrocatalytic Aldehyde Hydrogenation

-(C, O)-aldehyde adsorption configuration for C═O bond activation and facilitate a highly interconnected two-coordinated hydrogen-bonded network for directional H* transfer and suppressing the competitive hydrogen evolution reaction (HER). The presented Zn-EPT strategy for synthesizing ultrafine np-HEIs offers a general blueprint for designing high-efficiency electrocatalysts for electrocatalytic hydrogenation and other related applications.
