Ternary catalyst Mn-Fe-Ce/AlO for the ozonation of phenol pollutant: performance and mechanism.

In this study, a novel ternary catalyst Mn-Fe-Ce/AlO was synthesized by co-impregnation method, and was characterized by XRD, SEM, XPS, and FTIR. The catalytic performance of this ternary catalyst was evaluated in the heterogeneous catalytic ozonation of phenol pollutants and it improved the removal rate and mineralization degree of phenol pollutants. The changes of dissolved ozone in water and the TBA experiment proved that the ternary catalyst could accelerate the decomposition of ozone into hydroxyl radicals, thus accelerating the oxidation of phenol.
