Mesoporous silica KIT-6 with different pore sizes was controllably synthesized by hydrothermal methods. The same contents of Pt were loaded on KIT-6 supports to apply for propane total oxidation. Low-angle X-ray diffraction (XRD), nitrogen adsorption–desorption, CO chemisorption and transmission electron microscopy (TEM) were carried out to investigate the physicochemical properties of the catalysts...
Platinum was supported on γ-Al2O3 and ultra-stable Y zeolite (USY) by an incipient wetness impregnation method. The catalysts were characterized by nitrogen physisorption, transmission electron microscopy (TEM), CO/C3H8 isothermal oxidations, NH3 temperature-programmed desorption (NH3–TPD) and infrared (IR) spectroscopy of adsorbed probe molecules (CO, C3H8 and C3H8 + O2). Compared with Pt/Al2O3,...
