Promotion Effect of Microwave-Assisted Prepared Porous Fe–Mn Catalyst on Toluene Removal

Fe–Mn oxide is widely used for VOCs catalytic oxidation due to its advantages of low cost and easy availability. However, the low-temperature catalytic oxidation activity of Fe–Mn oxide is limited. In order to prepare a porous Fe–Mn oxide for VOCs oxidation with high efficiency and stability at low temperatures, a microwave-assisted oxalate co-precipitation method is used to prepare porous Fe2Mn1-MW catalysts, the physicochemical properties of the prepared porous Fe2Mn1-MW, such as surface structure, element composition, redox performance, oxygen mobility and oxidation activity, are compared with the porous Fe2Mn1 prepared by the conventional oxalate co-precipitation method. The results indicate that the porous Fe2Mn1-MW catalyst with microwave-assisted exhibits higher toluene conversion with a T90
