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.

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
Du et al designed and synthesized the core–shell FeCo@NG/NCNT, which presented excellent mass transfer capability and charge transfer properties, which can be effectively applied for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER).[15]
We have synthesized CoMn phosphide encapsulated in a nitrogen-doped graphene core–shell structure by the combination of the coprecipitation method and annealing treatment at high temperature
