Abstract

This research employed ozone modification technology to enhance the photocatalytic performance of ZnO. The findings indicated that ozone modification does not alter the crystal structure of ZnO. However, analyses using FTIR, XPS, and TEM revealed significant changes in the surface structure of the modified ZnO. Notably, the ability of the material to absorb visible light was improved, resulting in enhanced catalytic efficiency. Compared to unmodified ZnO, the ozone-modified ZnO demonstrated superior photocatalytic activity. Under simulated sunlight irradiation, the degradation efficiency of the ozone-assisted ultrasound-treated sample for methylene blue reached an impressive 99.6% within just 20 min, highlighting its promising application prospects.
