Abstract

In this paper, the DFT method is employed to analyze the sensing and adsorption performance intrinsic MoTe2 and Pt doped MoTe2 to the characteristic oil dissolved gases (C2H2, C2H4, CO, and H2). The value of binding energy demonstrates Pt atom prefer to be trapped at TMo site among TH, TMo, TTe, and TBr sites. Pt–MoTe2 depicts the excellent adsorption property to the four gases compared with MoTe2. Based on the change of band gap, the conductivity and sensitivity of Pt–MoTe2 decreases and increases after adsorption of four gases. The moderate recovery time reveals the higher gas-sensing and response of Pt–MoTe2 to C2H2 and C2H4 than to CO and H2. This paper provides theoretical guidance of potential application of a novel and high-performance gas sensor for online-monitoring the characteristic dissolved gases in transformer.
