| Abstract: | This present study revealed a dependence of rutile:anatase ratios in titania on the characteristics and catalytic properties of Co/TiO2 catalysts during CO hydrogenation. In this study, Co/TiO2 catalysts were prepared using various titania supports consisting of various rutile:anatase ratios of titania. In order to identify the characteristics, all catalyst materials were characterized using XRD, SEM/EDX, TPR, and hydrogen chemisorption. CO hydrogenation (H2/CO = 10/1) was also performed to determine the overall activity and selectivity. It was found that both activity and selectivity were altered by changing the rutile:anatase ratios in the titania support. |
