In this paper, we determine the range of potentials, which shows electrochemical stability and corrosion resistance of titanium and catalytically active electrodes based on it in 5 m of HClO4 solution. We reveal that the current-free potentials of these electrodes comply with compromise potentials conjugate reduction reaction of adsorbed oxygen and oxidation of hydrogen sulfide in the presence of hydrogen sulfide. Based on studies of properties of the semiconductor oxide electrocatalysts of transition metals, gas-diffusion electrodes are developed. It results in the selective anodic oxidation of hydrogen sulfide and allows creating the amperometric sensor for monitoring hydrogen sulfide in air and technological environments on their basis. This sensor surpasses basic technology characteristics of existing analogues of leading international manufacturers. The hydrogen sulfide sensor will contribute to enhancing safety and security in corrosion production that will intensify the development of oil and gas fields, improve the operation of communal services, as well as facilitate rapid analysis of forensic examinations.
