NOVELTY - Preparation of iron-nickel layered double hydroxide-molybdenum sulfide/nitrogen-doped graphene aerogel hydrogen evolution material involves mixing graphene oxide suspension with ethylenediamine, transferring the mixture to hydrothermal kettle, performing hydrothermal reaction to obtain nitrogen-doped graphene aerogel (NGA), preparing first mixed solution by mixing sodium molybdate, thioacetamide and water, adding first mixed solution to the reactor, performing hydrothermal reaction using NGA as a carrier, and obtaining molybdenum disulfide/nitrogen-doped graphene aerogel, adding ferric nitrate, nickel nitrate, ammonium fluoride and urea to obtained aerogel after mixing with water, leaving standstill to obtain the second mixed solution, transferring the second mixed solution to reactor for performing hydrothermal reaction, and drying. USE - Preparation of iron-nickel layered double hydroxide-molybdenum sulfide/nitrogen-doped graphene aerogel used as catalyst for electrocatalytic hydrogen evolution and oxygen evolution reaction (all claimed). ADVANTAGE - The iron-nickel layered double hydroxide-molybdenum sulfide/nitrogen-doped graphene aerogel hydrogen evolution material has low raw material cost, simple preparation method, good hydrogen evolution and oxygen evolution effect, high porosity, excellent mass transfer capability and low bulk density and dielectric constant, inherits excellent internal performance of graphene, and has large specific surface area. The high porosity and interconnected network structure of graphene oxide aerogel can improve material properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of iron-nickel layered double hydroxide-molybdenum sulfide/nitrogen-doped graphene aerogel hydrogen evolution material.
