Abstract
A hybrid three dimensional (3D) hydrogen evolution reaction (HER) catalyst that is formed from a porous Ni foam support, a NiSe2 scaffold positioned on the support; and layered transition metal dichalcogenide (LTMDC) or first-row transition metal dichalcogenide particles positioned on the NiSe2 scaffold. The catalyst provides a low onset potential, large cathode current density, small Tafel slopes, and large exchange current densities, similar in catalytic power to Pt HER catalysts.
