多金属非均相芬顿催化剂的开发与应用

Preparation and Application Performance of Multi MetalHeterogeneous Fenton Catalyst

该研究根据芬顿氧化技术存在的不足,利用金属掺杂共晶格技术,设计制备了多金属非均相芬顿催化剂。该催化剂利用表面电子云密度势能差,催化产生羟基自由基,进而对有机物表现出良好的催化降解效果。此外,该催化剂具有较宽的pH值相应范围与盐浓度相应范围,有效改善了芬顿氧化技术存在的不足。最后,该催化剂适用范围广,对于苯海拉明生产废水与电镀锌生产废水均表现出显著的有机物催化降解效果,具有良好的应用前景。

In this study,according to the shortcomings of Fenton oxidation technology,we designed and prepared multi metal heterogeneous Fenton catalyst by using metal doped co lattice technology.By potential energy difference of surface electron cloud density,the catalyst could catalyze the generation of hydroxyl radicals,and then showed good catalytic degradation effect on organic compounds.In addition,the catalyst had a wide range of pH value and salt concentration,which effectively improved the shortcomings of Fenton oxidation technology.Finally,the catalyst had a wide range of applications,and showed a good application prospect for the degradation of diphenhydramine wastewater and electroplating wastewater.
