蛋膜结构WO3纳米材料的制备及其H2S气敏性能
Preparation and H2S gas sensing properties of WO3 with eggshell membrane biomorphology
摘要
Abstract
The WO3 nano-material with eggshell membrane biomorphology was successfully prepared using eggshell membrane as a template by an easy and environment-friendly aqueous soakage technique followed by calcination treatment.The phase composition and microstructure of the prepared WO3 nano-material were characterized by XRD and TEM, and the gas sensing properties of gas sensors fabricated with the prepared WO3 nano-material was evaluated via the static volumetric method. The results show that the as-synthesized material is monoclinic WO3 which replicated the interwoven meshwork conformation of eggshell membrane exactly. The sensitivity of gas sensor to H2S (volume fraction of 30×10-6) reaches 89 at 200 ℃ with a short response time of less than 2 s.关键词
