Advanced low-temperature plasma oxidation catalytic technology is an advanced air pollution control technique that combines the advantages of low-temperature plasma technology and catalytic oxidation technology. It boasts low energy consumption, high energy utilization, high selectivity, high purification efficiency, and convenient application, making it promising for extensive use in environmental governance.

In a low-temperature plasma system, electrons are excited under the influence of an enhanced electric field, colliding with gas molecules (O2, H2O) and exciting them to a higher energy level. The high-energy molecules, with increased energy, cause bond breakage, producing strong oxidative free radicals ·O, ·OH, and OH2. Simultaneously, VOC molecules, upon collisional excitation by high-energy electrons, form small brittle fragments and atoms. These fragment groups and organic molecules are then removed under the action of strong oxidative groups and other active ions, ultimately converting into CO2, H2O, and other degradation products.
