摘要
A novel Co9S8-NixSy/Ni foam composite material was synthesized through the thermal decomposition of a cobalt-thiourea molecular precursor onto a 3D metallic support. The obtained electrode exhibited good activity toward the hydrogen evolution reaction in an alkaline medium, requiring a small overpotential of 163 mV at a current density of 10 mA cm(-2), which is one of the lowest ever reported among transition metal sulfide materials.
