Abstract

Phenol, as one of the organic pollutants in wastewater, is difficult to degrade, which will bring great problems to the environment and people. Ozone catalytic oxidation has a good effect on degradation of phenol. Bimetallic catalysts have been widely concerned in the degradation of phenol because of their high efficiency and low cost. In this work, flexible SiO₂ ceramic fiber membranes were prepared by electrospinning. Through impregnation, Fe₂O₃ and MnO₂ particles are also successfully loaded onto the SiO₂ fiber. Scanning electron microscope (SEM), X-ray diffraction (XRD), and Automatic specific surface area analyzer (BET) were used to characterize the material. Fe₂O₃-MnO₂ @ molecular sieve /SiO₂ has good catalytic activity for degradation of phenol. In this paper, a composite material of bimetal catalyst was developed. It provides a simple and effective method for the development of bimetallic catalytic materials for the degradation of phenol by ozone. The material is expected to be used in wastewater treatment.
