Abstract

CoMn phosphide encapsulated in a nitrogen-doped graphene core–shell structure was successfully prepared with Prussian Blue complexes as the precursor and P atom doping at a high temperature. The core–shell heterostructure demonstrates an impressive catalytic performance of hydrogen evolution reaction over a broad pH range, i.e., the overpotentials reach 159, 190 and 279 mV at a current density of 20 mA cm⁻² in the conditions of pH = 0, 14 and 7, and maintains excellent stability.
