NO<inf>2</inf>gas sensing of flame-made Pt-loaded WO<inf>3</inf>thick films
Unloaded WO 3 and 0.25-1.0 wt% Pt-loaded WO 3 nanoparticles for NO 2 gas detection were synthesized by flame spray pyrolysis (FSP) and characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM). The BET surface area (SSA...
