Carbonized Foam Supported Co 3 O 4 Activated Peroxymonosulfate Towards Rhodamine B Degradation

Co O has received much attention because of its excellent performance in activating peroxymonosulfate. However, the practical application of Co O has been seriously restricted by the problems of agglomeration of Co O , difficult separation, easy loss, and poor recycling. In this study, the CMF/Co O...

Summary:Co O has received much attention because of its excellent performance in activating peroxymonosulfate. However, the practical application of Co O has been seriously restricted by the problems of agglomeration of Co O , difficult separation, easy loss, and poor recycling. In this study, the CMF/Co O heterogeneous catalyst was prepared using the hydrothermal method. The crystal structure and morphology of CMF/Co O were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Rhodamine B (RhB) degradation was employed as a model test for evaluating potassium peroxymonosulfate (PMS) activation. The degradation rate of RhB can reach 98% in the catalyst dosage of 35 mg·L , PMS concentration of 50 mg·L , pH of 7, and RhB initial concentration of 10 mg·L after a 30 min reaction. The results showed that the degradation rate of RhB could be significantly improved by increasing the amount of CMF/Co O heterogeneous catalyst and the mass concentration of PMS. The degradation rate of RhB can be inhi
