Liu, Xian | Li, Xiaoya | Zhu, Lei | Wang, Xun
Herein, MI-Ag-TiO₂ was prepared by one-step sol-gel method, and its photocatalytic and characterization performance were fully analyzed. Within 120 min, the photocatalytic degradation rate of MI-Ag-TiO₂ to ethyl paraben was 93.4%, which was 1.48 times that of naked TiO₂. Compared with Ag-TiO₂, MI-TiO₂, and TiO₂, the photocatalytic selectivity of MI-Ag-TiO₂ to target pollutants increased by 24.5%, 31.5%, and 100%, respectively. Hence, the one-step molecular imprinting method can simply and quickly improve the photocatalytic performance of TiO₂. This research may help to further promote the practical application of molecularly imprinted photocatalysts in the future.
