This invention relates to a plasma generator based on a dense microporous material catalysis, belonging to the field of low-temperature plasma technology. The plasma generator contains at least one discharge unit, which includes a first electrode, a microporous ceramic medium, and a second electrode. The first electrode is used to connect to a power source, and the second electrode is used for grounding. The microporous ceramic medium is used to adsorb gas molecules and active particles generated by the plasma discharge. This invention generates micro-discharge in a dense microporous medium, which has an extremely high specific surface area. When gas passes through, it is adsorbed onto the surface of the micropores in the medium. Similarly, active substances in the plasma are adsorbed onto the surface of the micropores in the medium. This improves the contact efficiency between short-lived, highly active particles and free radicals in the plasma and the reactants, promotes surface catalytic reactions, and improves the overall efficiency of the device.
