Unleashing the Potential of Tailored ZnO–MgO Nanocomposites for the Enhancement of NO2 Sensing Performance at Room Temperature

Surface functionalization of semiconducting metal oxides has emerged as a highly effective approach for enhancing their sensing capabilities. In the present work, the surface of randomly oriented zinc oxide (ZnO) nanowires is modified with an optimized thickness (7 nm) of magnesium oxide (MgO), which exhibits an exceptionally sensitive and selective behavior toward NO
