在前文研究紫外光辐照下的光化学和光催化反应的某础上,本文进一步研究CdS、Pt/CdS粉末作为光催化剂,用可见光(碘钨灯)辐照SO_2水溶液体系的产H_2量和氧化率的规律性。实验步骤和分析方法如前文。实验结果如下:
Based on the previous studies on the photochemical and photocatalytic reactions under UV irradiation, we further studied the amount of H2O2 and the oxidation rate of CdS and Pt / CdS powders irradiated by visible light (iodine tungsten lamp) as photocatalyst Regularity. Experimental procedures and methods of analysis as described above. The experimental results are as follows:
