Study on the specific photodegradation performance of Fe3O4@SiO2@TiO2@MIPs for berberine hydrochloride

Abstract Adsorption is crucial for the performance of photocatalysts in degrading new pollutants. Here, we report a magnetic molecularly imprinted material Fe3O4@SiO2@TiO2@MIPs with a semiconductor/insulator/semiconductor structure, which achieved up to 81% preferential degradation of berberine 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.
