▎ 摘  要

NOVELTY - Graphene supported palladium catalyst comprises 2-10 pts. vol. material A containing 30-37% palladium chloride and hydrochloric acid at 0.01-0.1 g:10-40 ml ratio, 30-50 pts. vol. ethylene glycol, 100-150 pts. vol. graphene, and 5-20 pts. vol. titanoniobate nanosheet solution. USE - Graphene supported palladium catalyst used for synthesizing cinnamic acid (claimed). ADVANTAGE - The catalyst is environment-friendly, and produces high yield cinnamic acid. It has simple preparation, mild reaction conditions, and low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene supported palladium catalyst comprising dissolving palladium chloride in hydrochloric acid to obtain material A; mixing ethylene glycol and graphene using mixer, adding material A into mixer, mixing uniformly, adding titanoniobate nanosheet solution, and stirring for 20-40 minutes; feeding resulting mixture into photochemical reaction apparatus, setting apparatus at 4-6 amperes, 90-110 volts and 450-550 watts mercury lamp power, performing light reduction for 25-40 minutes, cooling at room temperature, centrifuging, discarding supernatant, washing with deionized water repeatedly to obtain viscous colorless supernatant, and collecting lower layer black viscous liquid or graphene supported palladium catalyst.
