Method for inducing discharge of internal micro-channel of porous material by plasma jet

A method for inducing discharge of an internal micro-channel of a porous material by plasma jet belongs to the technical field of plasmas, and can generate discharge plasmas in the internal micro-channel of a structured catalyst to improve the catalytic treatment effect of the plasmas. The method requires a plasma source 1 and a porous material 2. Wherein the plasma source 1 is an atmospheric pressure low-temperature plasma jet source. And the porous material 2 adopts a structured porous material of which the internal space structure and the size can be accurately adjusted, and comprises a micro-channel 21 and a cavity 22. The size of the microchannel 21 is in the range of tens of to hundreds of microns. The size of the cavity 22 is millimeter and is larger than the size of the micro-channel 21. One end of the micro-channel 21 is directly connected with the surface of the porous material 2, and the other end of the micro-channel 21 is directly connected with the cavity 22. The millimeter-level cavity connecte
