▎ 摘　　要

NOVELTY - A load-type palladium catalyst comprises graphene particles as carrier and loaded metal palladium (Pd) nano particles (0.05-10 wt.%). USE - A load-type palladium catalyst. ADVANTAGE - The catalyst provides simple technology and low cost; and has better structure stability, higher specific surface area, good degree of dispersion, high stability and high activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing load-type palladium catalyst by acid-washing graphene for 0.5-8 hours with inorganic acid (5-50 wt.%), neutralizing with water, and drying at 80-150 degrees C for 1-12 hours to obtain graphene carrier; immersing into solution containing Pd compound to obtain catalyst precursor; and aging for 0-48 hours, reducing with reducing agent for 0.5-24 hours at 20-150 degrees C, neutralizing, and drying.
