| 摘 要： | 以纳米锐钛矿型TiO2为光催化剂,对高聚物聚乙二醇水溶液进行光催化降解实验。生成物CO2的量及反应物剩余率与反应时间的关系表明该组反应为零级反应,且催化反应速率与平均相对分子质量成反比。根据热重分析、红外光谱的检测结果,对聚乙二醇光催化氧化反应的机理进行了探讨。

| Abstract: | The photocatalytic degradation of polyethylene glycol(PEG) was investigated using nano anatase TiO_2 as the photocatalyst.The change of the amount of CO_2 and the reactant with reaction time indicated that this was a reaction of zero order and the degradation rate of PEG was reciprocally-related with the molecular weight of PEG.The mechanism of oxidation of PEG was studied by meano of TG and FT IR. |
