Abstract:
The catalytic performance of catalyst can be increased by their structural properties, such as surface area and their crystal shape. In this study, ceria or cerium oxide with high surface area and ordered structure is prepared by nanocasting method using MCM-48 porous material, as a template. Optimal conditions of the nanocasting method are investigated to obtain ordered mesoporous ceria having high surface areas. The high surface area, 224.7 m²/g, and the ordered structure of cerium oxide are obtained at 50% weight of ceria using 30 min of stirring time at 100ºC of evaporated temperature. The resulting ordered mesoporous ceria is characterized using X-ray diffractometer (XRD), X-ray Fluorescence spectrometer (XRF), N₂ adsorption/desorption, Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), and Temperature programmed reduction (TPR).
