| Abstract: | KOH-modified TiO2 support was obtained by treating the hydrolysate of tetrabutyl titanate with KOH solution of various concentrations;the gold catalyst supported on the KOH-modified TiO2 was prepared through impregnation and used for CO oxidation.The support and catalyst were characterized by N2 physical sorption,thermogravimetry,thermo-analysis,X-ray powder diffraction,UV-vis diffuse reflection spectroscopy,transmission electron microscopy,and X-ray photoelectron spectroscopy.The results indicate that the ... |
