▎ 摘　　要

NOVELTY - Preparation of molybdenum-based alloy and graphene carbon material composite catalyst comprises ultrasonic dispersing graphene carbon material in 1-methyl-2-pyrrolidone at 20-30 degrees C for 1-3 hours, adding molybdenum nitrate solution to heavy metal and salt solution, mixing until uniform, adding sodium borohydride solid and reacting in hydrothermal reaction kettle at 20-200 degrees C for 4-48 hours. USE - Method for preparing molybdenum-based alloy and graphene carbon material composite catalyst (claimed). ADVANTAGE - Catalyst has good application prospect and economic benefit. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow diagram of molybdenum-based and graphene carbon material composite catalyst preparation (Drawing includes non-English language text).
