ABSTRAKT

Bimetallic Co-Cu/TiO2 catalyst was prepared through a co-impregnation method with anatase-TiO2 as support. The catalyst powder was shaped by three different binders (bentonite, polyvinyl alcohol, and polyethylene glycol) into extrudes. Samples were characterized using X-ray powder diffraction, temperature-programmed reduction (TPR), Brunauer–Emmett–Teller analysis, Barrett–Joyner–Halenda analysis, scanning electron microscopy (SEM), and energy dispersive X-ray techniques. Among the catalysts prepared, an optimal catalyst with the composition 65% TiO2 and a mixture of 1% polyvinyl alcohol, 2% PEG-1000, and 25% bentonite was selected with suitable properties. The specific surface area of the catalyst was found to be 127 m2·g-1 with a pore diameter of 9.28 nm. TPR results reveal that the presence of Cu lowers the reduction temperature of Co. The TPR profile is in good agreement with the results shown by SEM that the metal species were well dispersed over the TiO2 support.
