| 摘 要： | 测定了各种有机羧酸在Pt/TiO_2粉末悬浮体系中的光催化分解速度。不同分子结构的有机羧酸的光催化分解速度有明显的差别。通过计算与羧基相连的各种基团的诱导效应指数,发现基团的推电子能力对有机羧酸的光催化分解速度起主导作用,找到了有机羧酸光催化分解速度与其分子结构间的关系。

| Abstract: | The rate of photocatalytic decomposition of aqueous solutions of various organic car-boxylic acids with suspended Pt/TiO2 powder was determinated and the inductive effect index of organic groups attached on the carboxylic group was calculated. It was found that the influence of the electron pulling ability of attached group on the decomposition of organic carboxylic acid is the dominating factor. A relation between the rate of photocatalytic decomposition and the molecular structure of the organic acid was observed. |
