Two-dimensional titanium carbide (Ti3C2Tx) material with an organ-like morphology was prepared by a selective etching reaction strategy, and the surface-treated Ti3C2Tx samples were obtained by O2-Ar microwave plasma technology under different temperatures to regulate the terminal functional groups. The microstructure evolution and surface oxygen functional group changes of Ti3C2Tx were investigated at different plasma treatment temperatures. The effect of activated Ti3C2Tx on gaseous formaldehyde, benzene, toluene and xylene were analyzed. A possible gas-sensing mechanism was discussed based on the perspective of the variation of the surface oxygen functional groups. The results show that O2-Ar plasma treatment can increase the content of surface oxygen functional groups of activated Ti3C2Tx. The gas sensitive response of a sample treated by plasma at 500℃ can reach 169 for 0.01% formaldehyde at an optimal operating temperature, and this sample also exhibits a good selectivity to gaseous formaldehyde.
