Hydrogen gas is well-known pure fuel for which production water is inexhaustible and cheap source. However, water splitting reactions proceed only onto the surface of suitable catalysts. The effective electrocatalysts for hydrogen evolution reaction (HER) are Pt, Rh, and Ru. However, High price not allowed a wide their application in practice.
In the past decade, some metal dichalcogenides such as MoS2, TiS2 and MoSe2 have been reported as prospective electrocatalysts for HER from aqueous solutions. However, the efficacy of HER even onto the nanostructured MoS2 (MoSe2) is in order lower than onto the Pt. Besides, usually they are not stable and degradable. To avoid these problems, nanoplatelet and nanoparticulate MoS2 catalysts have been designed onto the metallic foams and in combination with carbon nanotubes or graphene species.
By this studie, the synthesis of the newelectrocatalysts on the base of nanostructured MoS2 array conjugated with other metals and/or organic molecule fragments will be investigate.
