Abstract
In the concurrent research era, doping transition metal dichalcogenides (TMDCs) with noble metals has drawn significant attention to enhance gas sensing performance. In this regard, we report for the first time a highly sensitive palladium doped WSe₂ (Pd-WSe₂) sensor for trace level detection of NO₂ gas at room temperature. The Pd-WSe₂ was synthesized by the combination of aerosol assisted chemical va-por deposition (AACVD) and hydrogen free simple atmospheric pressure chemical vapor deposition (APCVD) methods. Morphological and compositional analysis have revealed good yield for adsorbing the target gas. The sensor exhibited remarkable response towards 800 ppb NO₂ at room temperature even in the presence of humidity without applying any external stimuli. This finding will surely have high impact towards ongoing TMDCs based gas sensor research as well as environmental sustainibility.
