Abstract
The demand for highly sensitive and selective gas sensors for the detection of target gases in complex environments is rapidly increasing. In this study, we present a novel approach utilizing atomic layer deposition (ALD) technology to fabricate gas sensors based on metal-nanocluster functionalized 3D SnO2 nanotube arrays. Pd/Au-nanocluster-sensitized SnO2 sensors exhibit high sensitivity to formaldehyde, toluene, and acetone at room temperature, with detection limits of 1.2, 0.75, and 2.9 ppb, respectively. The selectivity of these sensors is due to the catalytic effect of metal nanoclusters on the SnO2 surface, which changes the density of states near the Fermi level and influences gas adsorption and…
