To improve the selectivity of gas-sensitive SnOx films, SnOx/MnOy composite structures were obtained in which manganese oxide plays the role of a NO2 sorbing filter. The microstructure and chemical composition of the films were characterized using scanning electron microscopy and X-ray photoelectron spectroscopy. The structures were tested to detect 5 ppm NO2 at room temperature. The sensory response of SnOx films in the presence of NO2 decreases by 16 times after coating the MnOy filter layer. Keywords: filters, microsensors, manganese oxide, tin dioxide.
