Abstract
The invention discloses a heterogeneous catalyst, a preparation method of the heterogeneous catalyst and application of the heterogeneous catalyst in hydrogen evolution by electrolyzing water. The heterogeneous catalyst comprises a carrier and an active component, the carrier is MXene; the active component comprises nickel phosphide and molybdenum diselenide; the active component has a heterostructure; the heterostructure comprises a Ni2P nanosheet and a MoSe2 nanosheet, wherein the Ni2P nanosheet and the MoSe2 nanosheet are formed on an MXene substrate. The Ni2P-coated MoSe2/MXene composite material disclosed by the invention has a heterostructure and a nanosheet array structure, and the structure has a rich structural network, greatly exposes active sites and shows excellent electro-catalytic performance.
