▎ 摘　　要

NOVELTY - Carbon dioxide reduction catalyst composition comprises porous graphene aerogel, cobalt nitrate, zinc nitrate, organic ligand, and polyvinylpyrrolidone in a mass ratio is 30-80:100:65-70:500-550:20-30. USE - Used as a carbon dioxide reduction catalyst. ADVANTAGE - The catalyst has good catalytic activity, good conductivity, low boiling point evaporation at high temperature, and high number of vacancies and pore structures in carbon matrix. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the carbon dioxide reduction catalyst comprising (i) adding graphene oxide and urea in distilled water solvent, ultrasonically dispersing in constant-temperature ultrasonic dispersion device, adding polyvinylpyrrolidone as cross-linking agent, continuously and ultrasonically processing, pouring solution to in reaction kettle, reacting at 170-190 degrees C for 10-15 hours, freeze drying to remove solvent, washing, and drying to obtain functional graphene aerogel, (ii) adding functional graphene aerogel to N,N-dimethylformamide solvent, uniformly and ultrasonically dispersing to add cobalt nitrate and zinc nitrate, allowing to stand for 12-24 hours, uniformly stirring to add organic ligand 4-amino-3,5-di-3-pyridyl-4H-1,2,4-triazole and surfactant polyvinylpyrrolidone, pouring solution in reaction kettle, reacting at 170-200 degrees C for 24-36 hours, centrifuging, washing, and drying to obtain cobalt-zinc-metal-organic frameworks supported graphene, and (iii) heating cobalt-zinc-metal-organic frameworks supported graphene in atmosphere furnace, thermally insulating, and calcining to obtain carbon dioxide reduction catalyst.
