The results of the development of gas chemical nanosensors with sensing elements based on molybdenum oxide, iron oxides, and chromium oxide are presented in the review. The developed devices are systematized in accordance with the features of the construction of their sensing elements; the groups of nanosensors based on molybdenum oxide, iron oxides, and chromium oxide are divided each into three subgroups. The analytical capabilities of these devices are considered and the observable regularities are noted. In particular, the potential of nanosensors in identifying a large number of inorganic and organic chemical compounds is demonstrated. The effect of the morphology and composition of the coating and temperature of the sensing element on the sensitivity and selectivity of the measurements and the response and recovery times is shown.
