摘要：以介孔γ-Al2O3为载体,采用化学沉积-光还原法制备了具有表面金属等离子体效应的Ag-AgCl/Al2O3复合光催化材料。用SEM、TEM、XRD及UV-Vis能谱等对复合材料进行了结构和性能表征,并以10 mg/L的亚甲基蓝(MB)溶液为目标降解物,对复合材料的光催化性能进行了评价。实验结果表明,复合光催化材料在可见光下光照60 min后对亚甲基蓝的降解率达95%以上,总有机碳TOC去除率约为65%,实验制备的Ag-AgCl/Al2O3具有很高的可见光催化活性,循环使用5次后依然具有90%以上的MB降解率。
The combination of a surface plasmon resonance photocatalyst Ag-AgCI and mesoporous Al2O3 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 absorptionspectra. 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 60min visible light irradiation. In addition, the obtained sample of Ag-AgCl/Al2O3 has higher activity under visible light irradiation and stable at 90% decolorized rate after recycling the photocatalytic reaction five times.
