چکیده انگلیسی
A self-heating effect has been observed in the gasochromic coloration of Pt coated WO3 (Pt-WO3) nanowire films, and its temperature rise rate is found to be strongly dependent on the initial temperature and the time of the sample exposed to air. X-ray photoelectron spectroscopy is applied to investigate the catalyst poisoning and reactivation of Pt-WO3 nanowires in air, and the results indicate that the Pt nanoparticles can be poisoned by chemisorbed oxygen atoms in air, causing the self-heating effect to be suppressed at room temperature. The mechanism response for the occurrence of the self-heating effect has also been discussed in depth.
