Abstract
The purpose of this work is to study the crystal structural, element composition, valence state and optical properties of the MIT-Ag/ZnO/Bi2WO6 in order to be used for antibiotic degradation application. MIT-Ag/ZnO/Bi2WO6 materials were prepared by sol–gel and ultrasonic composite method using cefuroxime sodium as the template molecule. The obtained catalyst was characterized by different techniques. The crystal structure was analyzed by XRD and FTIR. The elemental and valence composition were analyzed by XPS. It was found that the imprinting process did not changed the crystal structure, elemental composition and valence state of Ag/ZnO/Bi2WO6. The morphology was visualized by SEM. A heterojunction is formed between ZnO and Bi2WO6 as investigated by TEM analysis. The optical proprieties have been evaluated by DRS, a bandgap of 3.08 eV was found. PL results showed that the imprinting process inhibits the recombination of electron-hole pairs. Photocatalytic experiments were further carried out. MIT-Ag/ZnO/Bi2WO6 was selective to template cefuroxime sodium, and the degradation efficiency of cefuroxime sodium reached almost 100% under the irradiation of 250 W mercury lamp for 150 min. ·OH and h+ were the main active substances in the photocatalytic process.
