The catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. The catalyst was prepared by the wet impregnation method and characterized by using the Brunauer Emmett Teller (BET), field emission Scanning Electron Microscopy (FESEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and Temperature-programmed reduction (TPR) analysis. The highest catalytic ...

Vanadium-modified (SiO2/MgO/MgCl2)•TiClx Ziegler-Natta catalysts were prepared through co-impregnation of water-soluble magnesium and vanadium salts under different pH values. Several key factors such as pH value of co-impregnation solution during catalyst preparation, catalyst performances including catalytic activity, ethylene/1-hexene copolymerization and hydrogen response were investigated....

The Ni/P ratio of nickel phosphide has an important effect on the catalytic performance toward deoxygenation fatty acids to biofuel. Ni12P5 cluster is preferred model catalyst with butyric acid as reactant palmitic acid. mechanism over been theoretically investigated at GGA-PBE/DSPP, DNP level in dodecane solution. From acid, hydrodehydration predominated form n-butanal. Then, from n-butanal, l...
