Plasma device for decomposing greenhouse gas carbon dioxide

A plasma device for decomposing greenhouse gas carbon dioxide comprises a medium pipe, the upper end of the medium pipe is connected with a gas outlet, the lower end of the medium pipe is connected with a gas inlet, the gas outlet and the gas inlet are through holes and are communicated with the medium pipe, the medium pipe is provided with a high-voltage electrode, and a catalytic coating is arranged in the medium pipe; carbon dioxide can be continuously and efficiently adsorbed and decomposed based on the combination of a catalytic technology and a plasma technology. The catalyst coating on the inner wall of the device adopts ZnO modification and amino modification, active components are uniformly distributed, the surface activation effect of carbon dioxide is enhanced, the acting force with carbon dioxide is stronger, the decomposition effect of plasma on carbon dioxide is further enhanced, and the preparation process is simple, low in production cost, easy to implement and suitable for industrial producti
