▎ 摘　　要

NOVELTY - A zirconium-metal-organic frameworks (Zr-MOFs)/graphene composite photocatalyst contains zirconium-metal-organic framework-containing zirconium-benzenetricarboxylic acid-amino (Zr-BDC-NH2) compound and graphene composite material having sandwich-like structure in which graphene composite material contains 0.5-5 mass% graphene. USE - A zirconium-metal-organic frameworks/graphene composite photocatalyst for chemical synthesis of aromatic aldehyde (claimed). ADVANTAGE - Process is simple, easy to operate, safe, and environment-friendly and product maximizes low absorption and use of light and has improved photocatalytic performance and high selectivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of Zr-MOFs/graphene composite photocatalyst which involves using non-covalent assembly in situ solvothermal process; and (2) chemical synthesis of aromatic aldehyde which involves catalyzing composite photocatalyst into aromatic alcohol substance under excitation of visible light and performing highly selective oxidation.
