| 摘要: 制备了两种表面Schiff碱及其Cu2+、Co2+、Ni2+、Zn2+配合物,考察了它们对H2O2分解的催化性能,其活性顺序为:Co2+>Cu2+>Ni2+>Zn2+,且与金属离子氧化还原电位有关。溶液的pH值增加有利于催化反应,有机配体的加入则对反应有所抑制。 |

| Abstract: Two polymer supported Schiff bases (P-ensal and P-diensal) and related complexes with Cu2+, Co2+, Ni2+, and Zn2+ have been prepared and their catalytic activity for decomposition of hydrogen peroxide has been studied as a model reaction. The catalytic activity is greatly influenced by the rcdox potentials of the metal ions and the order is as follows:Co2+>Cu2+>Ni2+>Zn2+ The larger values of pH increase the catalytic activity, while adding organic adducts, such as phcn, Im, py, or bipy, would restrain the reaction. |
| Keywords: supported Schiff base complex catalysis decomposition of H2O2 |
