Mechanism of Annealing Treatment Effect on the Gasochromic Properties of WO3 Bulks and Films

摘要：

　　Nanostructural WO3 materials exhibit excellent gasochormism performance under the action of the hydrogen gas.In this paper,we study the mechanism of annealing treatment effect on the gasochromic properties both of the WO3 bulks and WO3 films.WO3 bulks were prepared from WO3 sol and dried under ambient pressure,which was previously synthesized via sol-gel method.The WO3 films were prepared using dip-coating method.UV-visible spectroscopy,Raman spectroscopy,Fourier transforms infrared spectroscopy (FT-IR) and X-ray diffraction spectra (XRD) were utilized to investigate components,structures and gasochromic properties.And we find that the mechanism of the thermal treatment on the gasochromic performance depends on H+ diffusion velocity which largely relies on the structural water content.
