Abstract

Most of volatile organic compounds (VOCs) are often harmful or even toxic for environment, which require in situ detection. Here, we demonstrate that the TiO₂ additive can enhance significantly gas-sensing properties of the SnO₂-based sensor to VOCs, independent of its content and the concentration of tested gases. The improved gas-sensing quantities of matter, i.e., maximum sensitivity, minimum gas concentration, optimal operating temperature, and response and recovery times, are found to satisfy the basic needs for a practical application, which renders the TiO₂SnO ₂ composite material promising for the development of sensor devices to VOCs.
