Characterization by XRD, Raman, HRTEM, XPS, Received in revised form 28 July 2015 H -TPR, O -TPD, CO -TPD and NH -TPD revealed that Ce Ti O catalysts were identified as the forms of 2 2 2 3 1−x x 2 Accepted 29 July 2015 fluorite, monocline and anatase. The incorporation of Ti distorted the crystal structure and thus increased Available online xxx greatly the acidity and the oxygen mobility at high temperature. Ce Ti O catalysts had considerable
