Composite Catalyst for the Photocatalytic Isomerisation of Norbornadiene to Prepare Quadricyclane and Process for Making the Catalyst |
摘要 |
The present invention discloses a composite catalyst for the photocatalytic isomerisation of norbornadiene to prepare quadricyclane, comprising: a solid photocatalyst, selected from the group consisting of TiO2, Ti-MCM-41, Ti-SBA-15, ZnO, WO3, Ta2O5 or SrTiO3; and an organic photo-sensitizer loaded on the surface or in the channel of said solid photocatalyst, selected from benzophenone, acetophenone, Michler's Ketone, tetraethyl Michler's Ketone, and diethyl Michler's Ketone, where the organic photo-sensitizer is present in the solid photocatalyst in an amount of 0.5% to 20% by weight. The catalyst of the invention can catalyze a target reaction under the condition that no solvent is used, and the yield of the target product quadricyclane is higher. Furthermore, the catalyst of the invention has a stable activity, and it can be recycled. The invention further discloses a process for preparing the composite catalyst. |
