CdS、Ag+掺杂改性纳米TiO2光催化降解有机物研究
Research on Photocatalytic Degrading Organic Material of Nano-TiO2 Modified by CdS,Ag+
【摘要】 在理论分析的基础上对纳米TiO2分别进行掺CdS和掺银改性实验研究。采用XRD和粒度分析技术对改性后的样品进行表征,并以掺杂CdS、Ag+纳米TiO2进行光催化降解甲基橙模拟实验。结果表明,掺杂CdS、Ag+纳米TiO2在可见光范围内降解有机物的效率有较大提高。
【Abstract】 The experimental investigation on nano-TiO2 property modified with CdS,Ag+ doping was carried out based on the theoretical analysis.The property of the modified nano-TiO2 was characterized with XRD and grading methods.The appraisal of the effects of TiO2 properties modified with the two doping substances was made on the experiment by the doped nano-TiO2 photocatalytic degrading methyl hesperidin.The results show that efficiency of degrading organic substance with doped nano-TiO2 within visible light spectrum is greatly improved,and the degrading efficiency of photocatalysis with CdS is higher than that doped nothing.
