▎ 摘　　要

NOVELTY - An electrocatalyst is formed by growing a nano-structured molybdenum disulfide/cobalt sulfide composite on a three-dimensionally crosslinked gel-type graphene/carbon nanotubes base material. USE - Electrocatalyst is used for electrolysis of water in production of hydrogen (claimed). ADVANTAGE - The electrocatalyst provides fast electron transfer path and ion transport channel due to presence of three-dimensionally crosslinked gel-type graphene/carbon nanotubes base material, and uses the nanostructured molybdenum disulfide/cobalt sulfide which anchors more electroactive sites on three-dimensional structure carbon, thus enhancing electrochemical hydrogen evolution performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the electrocatalyst.
