Ag-AgCl/Al2O3复合光催化材料的制备与光催化性能研究
Preparation and Photocatalytic Activity of Ag-AgCl/Al2O3 Composite Photocatalyst
摘要
Abstract
The combination of a surface plasmon resonance photocatalyst Ag-AgCl and mesoporous A12O3 carrier were prepared by chemical precipitation and photochemical reduction method. The structure and performance of the obtained samples were characterized by SEM, TEM, XRD and UV-Vis absorption spectra. The photocatalytic properties of catalyst have been studied with 10 mg/L concentration methylene blue solution to be degraded under a visible light source. The experimental results showed that the degradation rate of methylene blue could be more than 95% and the removal rate 65% TOC, under 60 min visible light irradiation. In addition, the obtained sample of Ag-AgCl/Al2 O3 has higher activity under visible light irradiation and stable at 90% decolorized rate after recycling the photocatalytic reaction five times.关键词
