Abstract

In an effort to develop a long-lasting gas sensor, this article presents titanium nitride (TiN) as a potential substitute sensitive material in conjunction with (copper(II) benzene-1,3,5-tricarboxylate) Cu-BTC-derived CuO. The work focused on the gas-sensing characteristics of TiN/CuO nanoparticles in detecting H₂S gas at various temperatures and concentrations. XRD, XPS, and SEM were utilized to analyze the composites with varied Cu molar ratios. The responses of TiN/CuO-2 nanoparticles to 50 and 100 ppm H₂S gas at 50 °C and 250 °C are 34.8 and 60.0, respectively. The related sensor had high selectivity and stability towards H₂S, and the response of TiN/CuO-2 is still 2.5-5 ppm H₂S. The gas-sensing properties as well as the mechanism are fully explained in this study. TiN/CuO might be a choice for the detection of H₂S gas, opening up new avenues for applications in industries, medical facilities, and homes.
