▎ 摘 要
NOVELTY - Sulfur-doped graphene-supported cadmium-molybdenum-based catalysts comprises 15-20 pts. wt. graphite oxide, 5-10 pts. wt. hydrogen sulfide, 10-15 pts. wt. cadmium salt and 4-6 pts. wt. molybdate. USE - Sulfur-doped graphene-supported cadmium-molybdenum-based catalysts used for synthesizing low carbon alcohols in carbon dioxide. ADVANTAGE - The catalyst has high loading, high specific surface area, high catalytic activity, good selectivity and mild reaction conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of sulfur-doped graphene-supported cadmium-molybdenum-based catalysts comprising mixing oxidized graphite and 1000 times ultrapure water, stripping for 4-8 hours to obtain uniformly dispersed graphene oxide, freeze drying graphene oxide at -80-50 degrees C for 8-10 hours to obtain oxide graphene gas gel, heating oxidized graphene gas gel under nitrogen atmosphere at 1100-1200 degrees C, introducing hydrogen sulfide gas, reacting for 4-6 hours to obtain sulfur-doped graphene, pulverizing sulfur-doped graphene airgel into powder, adding 100 times ultra-pure water, dispersing for 30-60 minutes, adding cadmium salt solution, mixing, adjusting pH to 8-8.5, filtering, washing, transferring solids to 0.3 times ultrapure water, heating at 100-120 degrees C, mixing at 200-300 revolutions per minute, dropping molybdate, reacting for 18-24 hours, filtering, washing and drying.
