Determination of hydrogen-containing gases in air with SnO2-based sensors

Methods of monodisperse SnO2 crystallites and SnO2-TiO2 composites synthesis were developed. Obtained materials were studied using SEM, TEM, FTIR, XRD methods. Sensors based on these materials were made, and their capability of detecting hydrogen in dry and humid air was investigated. Several differ...
