制备Fe3O4@PCDP纳米复合材料作为高效、环境友好的异相类芬顿催化剂，探究其对罗丹明B（RhB）的降解性能。借助XRD、FTIR和SEM等方式对Fe3O4@PCDP纳米复合材料的结构进行表征，结果显示催化剂成功制备。并探究H2O2用量和pH对罗丹明B降解效果的影响。在最佳反应条件下，反应42 h后RhB去除率可达到87.25%。循环3次依然具有较好降解效果，且催化剂结构未变化，催化性能稳定。
In this study, a Fe3O4@PCDP nanocomposite is prepared as a highly efficient and eco-friendly heterogeneous Fenton-like catalyst that is used for the degradation of Rhodamine (RhB). The structure of the Fe3O4@PCDP nanocomposite is characterized by XRD, FTIR, and SEM, and the results demonstrate that it is synthesized successfully. The catalytic capacity of Fe3O4@PCDP is evaluated on the basis of various parameters, including the concentration of H2O2 and the pH value. The removal rate of RhB reaches 87.25% 42 h after the reaction under the optimal condition. The structure of Fe3O4@PCDP does not change and the catalytic performance is stable after the third cycle.
