摘要：

The gas sensitivity and dynamic characteristics of SnO2 and ZnO thin-film resistive-type sensors are studied in mixtures of hydrocarbons, carbon monoxide and hydrogen with air and helium. It is shown that application of adsorbing catalytic coatings (silicasol, ZnO with tetraethylsilane) on a ZnO layer results in an augmentation of the sensor gas sensitivity and a decrease of its response time
