| 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 mat... |
