Abstract
Abstract Rationalizing non‐precious pH‐robust electrocatalysts is a crucial priority and required for multi‐scenario hydrogen production customization. Herein, an amorphous–crystalline CoBO x /NiSe heterostructure is theoretically profiled and constructed for efficient and pH‐robust water electrolysis. The crystalline lattice confinement induces a CoCo bond shortening and a B‐site delocalization on amorphous CoBO x , resulting in a decreased d‐p band center difference (Δε d‐p ) toward the balanced intermediates adsorption/desorption. Accordingly, the CoBO x /NiSe heterostructure exhibits efficient and robust hydrogen/oxygen evolution reaction (HER/OER) catalytic activity in different electrolytes. Of…
