The detection of low-concentration gases and odors in fields such as healthcare, mobility, indoor environment control is attracting tremendous attention. development high-sensitivity gas sensors capable detecting low concentrations molecules strongly desired. This review focuses on tin oxide nanomaterials, which are substances that being actively researched semiconductor-type sensors. In particular, the novel nanomaterials over last decade their sensing applications discussed. It revealed dimension morphology affect performance. Tin having nano-meter size similar to a depletion layer, controlled microstructure nanosheet structure shows high dendritic 2D nanosheets connected by crystal growth points direction for future sensor development. Furthermore, adsorption performance reactivity metastable plane will be guide
