Abstract

Adsorption is crucial for the performance of photocatalysts in degrading new pollutants.Here,we report a magnetic molecularly imprinted materialFe3O4@SiO2@TiO2@MIPswith a semiconductor/insulator/semiconductor structure,which achieved up to 81%preferential degradation of berberberine hydrochloride(BH)。The significant enhancement of catalytic performance can be attributed to the interaction between BH and the imprinted cavity,as well as size matching,which proposes new solutions to address the current problem of difficult degradation of new pollutants。

The semiconductor/insulator/semiconductor structure of Fe3O4个@SiO2@TiO2effectively inhibits the generation of undersirable heterojunctions between TiO2and Fe3O4个单击功能区上,BH after constructing a molecularly imprinted layer on the TiO2layer on the surface.During the photodegradation of BH,holes and superoxide radicals dominate the degradation of BH。
