According to the preparation process, the magnetic fenton catalyst spinel ferrite is prepared from iron sludge generated in the fenton process, and nitrate of divalent metals (such as nickel, manganese, zinc, barium and cobalt) as raw materials by adopting a coprecipitation method; and the spinel...
To improve this, defect engineering is a valuable method for regulating the electronic structure and coordination environment. Herein, this manuscript discusses the use of defect spinel oxides in electrocatalytic reduction reactions, including the different types of defects, construction methods, and ...
Then, the synthesized sample was used as the photo-Fenton heterogeneous catalyst for the discoloration of methyl orange (MO) in solution. The XRD results show that the synthesized sample was pure, only with the spinel structure, when the volume ratio of the fresh egg white/ferric nitrate/zinc...
Finally, the mechanism for MO discoloration in the photo-Fenton system was discussed.Ping LiHuan-Yan XuXue LiWei-Chao LiuYan LiCEAM 2012Li P,Xu H Y,Li X,et al.Preparation and Evaluation of a Photo-fenton Heterogeneous Catalyst:Spinel-typed ZnFe2O4. Advanced Materials Research . 2012...
