Abstract: The electrocatalyst for hydrogen evolution reaction includes nanosheets of molybdenum disulfide (MoS2) deposited on a carbon fiber substrate. The catalyst is formed in stepwise fashion by chemical vapor deposition of nanosheets of MoO3 onto the substrate, then reducing the MoO3 to nanosheets of MoO2 using sublimed sulfur, then by reaction of sulfur vapor with the MoO2 to form nanosheets of MoS2 on the carbon fiber substrate. The catalyst is multifaceted, having a large density of edges providing catalytically active sites for the hydrogen evolution reaction. The activity of the catalyst is enhanced by coating the catalyst with spherical fullerenes (nC60).
