Sponge loaded photocatalyst and application thereof

Abstract

The invention provides a sponge loaded photocatalyst, which is prepared from sponge, a Linker reagent and a photocatalyst, wherein the sponge contains surface groups; the Linker reagent at least contains two active functional groups; the photocatalyst is an organic photocatalyst or a metal complex photocatalyst; the Linker reagent is chemically bonded with the surface groups of the sponge through the active functional groups, and is then loaded on the surface of the sponge; and the photocatalyst is connected onto the surface of the sponge through being bonded with the active functional groups of the Linker reagent.

Description

technical field

[0001] The invention belongs to the field of catalysts, in particular to a sponge-supported photocatalyst and its application. Background technique

[0002] Photocatalyst is a chemical substance that can play a catalytic role under the excitation of photons. It usually uses visible light as a light source and is a green and efficient catalytic substance. The application of photocatalysts in cross-dehydrocoupling reactions has attracted increasing attention. Since the photocatalyst itself does not participate in the reaction, it is possible to recycle the tried photocatalyst in principle. However, in the traditional homogeneous photocatalytic reaction, due to the troublesome post-processing process, the used photocatalyst is usually discarded, resulting in a great waste of photocatalyst. In particular, metal complex photocatalysts cause great pollution to the environment after they are discarded. Loading photocatalysts is an effective way to reduce waste an...
