title: Enhanced activity for CO oxidation over WO3 nanolamella supported Pt catalyst.
abstract: WO3 nanolamella supported Pt catalyst has been prepared and applied for CO oxidation in this work. A significantly enhanced activity has been achieved, compared to that of the Pt catalyst supported by the WO3 nanoparticle. The catalyst characterization using X-ray diffraction (XRD), scanning electronic microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), and N2 adsorption-desorption confirms that the WO3 nanolamella supported Pt catalyst possesses higher Pt dispersion, improved metal-support interaction with a higher electron density of Pt, and a weak adsorption of CO, leading to the significantly enhanced activity for CO oxidation.
