ABSTRACT
In the present work, the successful fabrication of highly sensitive formaldehyde sensor based on ZnO doped Pd and Pt nanoparticles. The Pt-Pt/ZnO has been synthesized through a simple, facile and rapid method and characterized by several techniques. The fabricated Pt-Pt/ZnO exhibited a very high HCHO gas sensor response of 289.2 to 10 ppm, good selectivity and experimental detection limit of 0.5 ppm at room temperature. Response and recovery times for formaldehyde are 96 s and 46 s, respectively, at room temperature. Therefore, Pt-Pt/ZnO is a promising application in the field of detection of formaldehyde.
