▎ 摘　　要

NOVELTY - Preparing a molybdenum sulfide/nitrogen-doped graphene and carbon nanofiber composite material with a stacked structure, comprises generating nitrogen-doped graphene by thermally condensing urea into carbon nitride and heating and pyrolyzing again, carbonizing bacterial cellulose chain polymers into nano-carbon fiber materials, through the high temperature pyrolysis of the mixture of urea and bacterial cellulose, obtaining the veins of carbon nanofibers, rinsing the bacterial cellulose film repeatedly with deionized water, immersing in urea solution, adding aminated molybdenum sulfide or its hydrate, and placing in refrigerator to freeze into solid, freeze-drying frozen sample, placing white airgel in a tube furnace heating at 900-1100℃ for one hour, and naturally cooling to room temperature under nitrogen gas, and obtaining black carbon aerogel and a matrix composite material of stacked molybdenum sulfide/nitrogen doped graphene and carbon nanofibers. USE - The method for preparing molybdenum sulfide/nitrogen-doped graphene and carbon nanofiber composite material with stacked structure useful as catalyst material for preparing hydrogen by electro-catalysis hydrolysis (claimed). ADVANTAGE - The method enables to prepare molybdenum sulfide/nitrogen doped graphene nano-carbon fiber composite material, which has high purity, and enhances the electric catalytic effect of the nitrogen-doped graphene and hydrogen evolution reaction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a stack structure of molybdenum sulfide/nitrogen doped graphene nano-carbon fiber composite material.
