| 英文摘要 | Tungsten oxide is a kind of multifunctional materials with excellent properties for gas sensing, electrochromic and photocatalytic applications. In this study,Tungsten oxide nanoplate thin film was prepared by hydrothermal methods. The as-prepared thin film is composed of tungsten trioxide hydrate nanoplates, which are randomly orientate on the surface. The as-grown nanoplate thin film shows good sensitivity to H-2 gas. Dehydration and phase transition to gamma-phase tungsten trioxide were found after annealing, and the sensitivity as well as the response time to H-2 were improved. We found that the nanoplate in the annealing sample bursts, which raises the surface -to-volume ratio for better hydrogen diffusion and reaction. The sensing mechanism was discussed. The findings provide a way to control the structure and surface morphology for improving the H-2 sensing properties of tungsten oxide. |
