NOVELTY - An electrochemical hydrogen evolution catalyst comprises reduced graphene oxide carbon nanotube aerogel, and molybdenum sulfide supported on the pores and surface of the aerogel network structure. The aerogel and molybdenum sulfide are in a mass ratio of 1-10:2. USE - Electrochemical hydrogen evolution catalyst. ADVANTAGE - The catalyst has higher stability, and exhibits excellent electrochemical hydrogen evolution characteristics due to loading of molybdenum sulfide on aerogel, which improves the number of active sulfur atoms exposure, dispersibility of the active material, and electron transfer rate. DETAILED DESCRIPTION - An electrochemical hydrogen evolution catalyst comprises reduced graphene oxide carbon nanotube aerogel, and molybdenum sulfide (Mo3S13) supported on the pores and surface of the aerogel network structure. The aerogel and molybdenum sulfide are in a mass ratio of 1-10:2. An INDEPENDENT CLAIM is included for preparation of the catalyst, which involves preparing purified Mo3S13 crystal, preparing reduced graphene oxide carbon nanotubes aerogel, and preparing composite of molybdenum sulfide (Mo3S13) and reduced graphene oxide carbon nanotubes aerogel by dispersing molybdenum sulfide (Mo3S13) and aerogel, in N,N'-dimethylformamide, and sealing at 100-300 degrees C for 8-20 hours.
