Abstract
A highly active and exceptionally durable non-noble metal-sulphide based Hydrogen Evolution Reaction (HER) catalyst and the preparation thereof. More particularly, provided is a highly active earth abundant metal-sulphide based HER catalyst with exceptionally durable hydrogen evolution activity even after 100 hrs.
Claims6
A Hydrogen Evolution Reaction (HER) catalyst comprising a 3R-MoS2-NixSy catalyst;
- wherein x=1,3 and y=1,2,4.
A method of synthesizing a HER catalyst comprising 3R-MoS2-NixSy catalyst;
- wherein x=1,3 and y=1,2,4, wherein said catalyst is synthesized by a hydrothermal process comprising the steps of:
- (a) dissolving (NH4)6Mo7O24·4H2O (Ammonium molybdate tetrahydrate), Ni (NO3)2·6H2O (Nickel nitrate hexahydrate) and (NH4)2CS (Thiourea) in water;
- and
- (b) maintaining the reaction mixture at a temperature in the range of 150-250° C. for the period of 8-16 hrs in an autoclave reactor to afford black colored product of 3R-MoS2-NixSy catalyst;
- wherein x=1,3 and y=1,2,4.
