| 摘要 |
Disclosed is a composite catalyst used in preparing quadricyclane through photocatalytic isomerization of norbornadiene, the composite catalyst comprising: a solid photocatalyst selected from TiO2, Ti-MCM-41, Ti-SBA-15, ZnO, WO3, Ta2O5 or SrTiO3; an organic photosensitizer loaded on the surface or pores of the solid photocatalyst, the organic photosensitizer being selected from benzophenone, acetophenone, Michler's ketone, tetraethyl Michler's ketone, and diethyl Michler's ketone, the organic photosensitizer accounting for 0.5%-20% of the solid photocatalyst by weight percentage. The catalyst can catalyze a target reaction without the use of a solvent, with a high yield of target product quadricyclane, and the catalyst has stable activity and can be used repeatedly. Also disclosed is a composite catalyst preparation method. |
