Abstract: A method for enhancing degradation of ester volatile organic compounds with a cerium oxide supported palladium single atom catalyst under low-temperature microwave comprises the steps of firstly preparing a single atom catalyst Pd/CeO2, adding the catalyst Pd/CeO2 into a reaction cavity, initiating microwave radiation to enhance the catalysis reaction, and quickly introducing an ester compound with a concentration of 50˜5000 mg/m3 and a space velocity of 2000˜100000 h?1 into the reaction cavity from a vapor phase sampling port to react when the reaction temperature is 10˜80° C. A catalyst packed column is provided in the reaction cavity, the vapor phase sampling port is defined at the bottom of the reaction cavity, and an exhaust port is defined at the top of the cavity. The microwave method can enhance and activate active sites, prevent the aging of active sites, and enable the chemical reaction rate to be increased by more than 17.9%.
