Photo-assisted heterogeneous Fenton catalyst as well as preparation method and application thereof

The invention discloses a photo-assisted heterogeneous Fenton catalyst as well as a preparation method and application thereof, and belongs to the technical field of water treatment materials. Gamma-Al2O3 pellets are put into a certain amount of a solution containing Ce < 3 + > to be doped with Ce, the reaction activity is remarkably improved, stirring is conducted in a solution containing Fe < 2 + >, an H2O2 solution is added for a reaction, the delta-FeOOH/CeO2/gamma-Al2O3 composite material is obtained, a novel photo-assisted heterogeneous Fenton system is constructed, efficient generation of. OH is achieved, and the preparation method has the advantages that the preparation process is simple, and the preparation cost is low. COD (Chemical Oxygen Demand) and residual antibiotics in the antibiotic wastewater can be effectively degraded and removed. 本发明公开了一种光辅助非均相芬顿催化剂及其制备方法与应用，属于水处理材料技术领域。本发明通过将γ-Al2O3小球放入一定量的含Ce3+溶液掺杂Ce，显著提高反应活性，并且在含Fe2+溶液中搅拌，加入H2O2溶液进行反应，得到δ-FeOOH/CeO2/γ-Al2O3复合材料，并构建一种新型的光辅助非均相芬顿体系，实现·OH
