Abstract: Binary (ZnO, Fe$_2$O$_3$) and ternary (ZnFe$_2$O$_4$) gas-sensitive oxide materials are synthesized, and the correlation between their sensitivity to ethanol vapor and the functional chemical composition of the surface is studied by X-ray photoelectron spectroscopy and by the technique of the adsorption of acid-base indicators. It is found that the sensitivity to ethanol increases with increasing content of Brönsted acid sites with the acidity index рK$_a\approx$ 2.5 and with increasing percentage of surface oxygen involved in OH/CO$_3$/C–O groups. This interrelation is attributed to the specific features of interaction between ethanol molecules and hydroxyl groups on the surface of the oxides.
