英文摘要Sulfate radical based advanced oxidation process has received popular attention in organic pollutants degradation recently, including which, cobalt ferrite heterogeneous catalyst was reported to be an effective activator. However, issues of particle aggregation and metal leaching still made the activity and stability not so satisfactory. In this study, well-defined partially inverse spinel cobalt ferrite/mesoporous silica ((Co (x) Fe1-x )[Co1-x Fe1+x ]O-4@mSiO(2)) nanostructured catalysts with uniform yolk/shell architecture were synthesized successfully through a hard-templating method for the first time. The prepared catalysts were characterized by various techniques including X-ray diffraction, transmission electron microscopy, N-2 physical adsorption/desorption. And moreover, Mossbauer spectroscopy was employed to confirm the detailed structure of the partially inverse spinel cobalt ferrite. It was shown that the synthesized catalysts consisted of (Co0.21Fe0.79)[Co0.79Fe1.21]O-4 nanoparticles encapsulated in mSiO(2) hollow spheres and the content of cobalt ferrite can be controlled by varying experimental conditions. The catalysts were utilized as peroxymonosulfate catalytic activator for organic pollutant degradation. Both sulfate radical and hydroxyl radical were certified as intermediate active species during the dye pollutants degradation process. Compared to the conventional mSiO(2) supported and naked cobalt ferrites, the yolk/shell nanostructured catalysts exhibited higher activity, excellent reaction stability and sintering resistance. It is clear that the design of such yolk/shell architecture can promote the development of highly efficient catalytic nanomaterials applied to degradation of organic pollutants.
