以甲基橙作为脱色对象 ,对二氧化钛、氧化锌和硫化镉的光催化现象进行了对比研究 ,发现他们都具有明显的光催化脱色效果 ,其中硫化镉的脱色效果最好。掺杂银后 ,各种光催化剂的脱色效果又都有明显的提高。此外还对氧化锌的寿命进行了测试
Methyl orange as a decolorizing object, titanium dioxide, zinc oxide and cadmium sulfide photocatalytic phenomena were compared and found that they both have a significant photocatalytic decolorization effect, of which the best effect of cadmium sulfide decolorization. After doping silver, the decolorization effect of various photocatalysts has also been significantly improved. In addition, the life of zinc oxide has been tested
