Polyaniline/WO 3 nanofiber composite-based surface acoustic wave (SAW) gas sensor has been investigated towards hydrogen (H 2 ). Chemical oxidative polymerization of aniline was employed to synthesize polyaniline nanofibers with WO 3 nanoparticles. The nanocomposite was deposited onto a layered ZnO/64° YX LiNbO 3 SAW transducer. The sensor was exposed to various concentrations...
This paper focuses on the microstructural characterization of the MoO 3 -TiO 2 nanocomposite thin films prepared by the sol-gel process. The MoO 3 -TiO 2 thin films were prepared by Mo(OC 2 H 5 ) 5 and Ti(OC 4 H 9 ) 4 precursor solutions. Different atomic ratios of the two compounds were investigated. The thin films were...
