On one hand, the strong electric field can prevent the effective active photoproduction electron and photoproduction hole from being compounded in the photocatalysis process; on the other hand, the photocatalyst has a synergistic excitation effect, when air containing volatile organic molecules or odor gas molecules and free bacteria passes through the photocatalyst area, the air is adsorbed on the surface of the photocatalyst and then decomposed, and the effects of purifying the air and eliminating odor are achieved. The needle point discharge electrode 7 continuously releases negative ions and trace ozone under the action of the high-voltage power supply 6, and flora around the device is killed along with the diffusion effect of the fan 13, so that the killing effect is achieved.
