Mo-doping heterojunction: interfacial engineering in an efficient electrocatalyst for superior simulated seawater hydrogen evolution.

ABSTRACT: Exploring economical, efficient, and stable electrocatalysts for the seawater hydrogen evolution reaction (HER) is highly desirable but is challenging. In this study, a Mo cation doped Ni_0.85Se/MoSe₂ heterostructural electrocatalyst, Mo_x-Ni_0.85Se/MoSe₂, was successfully prepared by simultaneously doping Mo cations into the Ni_0.85Se lattice (Mo_x-Ni_0.85Se) and growing atomic MoSe₂ nanosheets epitaxially at the edge of the Mo_x-Ni_0.85Se. Such an Mo_x-Ni_0.85Se/MoSe₂ catalyst requires only 110 mV to drive current densities of 10 mA cm^-2 in alkaline simulated seawater, and shows almost no obvious degradation
