Characterization of Pt-doped WO<inf>3</inf>nanoparticles synthesized by flame spray pyrolysis

Undoped WO3and WO3nanoparticles doped with 0.25-1.0 wt.% Pt were successfully produced in a single step by flame spray pyrolysis (FSP) [1]. Tungsten (VI) ethoxide 5% w/v in ethanol 99.8% and platinum (II) acetylacetonate were used as W and Pt precursors respectively dissolved in ethanol. The undoped...
