摘要：In this work, the g-C3N4/V2C MXene composite catalyst was prepared by solvothermal method, and its denitration performance under synergistic plasma (NTP) was investigated. The results showed that when the mass ratio of V2C is 3%, the denitration performance of V-CN-3-NTP is as high as 83.3%, which is 1.2 and 2.1 times that of the V2C-NTP and g-C3N4-NTP systems alone. The apparent morphology, phase structure, and catalytic mechanism of the catalyst were studied by SEM, TEM, XRD, FTIR, XPS, etc. The results showed that g-C3N4grows well on V2C mxene. V2C is not only an electron acceptor but also an active site for NO adsorption. The electrons and holes generated by V2C could be effectively separated by the high-voltage electric field, which improves the denitration performance and shows a good synergistic effect.
