Abstract:

This paper describes our research efforts towards the preparation of high surface area ceria oxide CeO2 containing catalysts for fuel processing and therefore for fuel cells applications. In the present work, we present a simple. single step flame synthesis method to prepare high surface area ceria based fuel reformation catalysts using aqueous solutions of metal acetate precursors. The specific surface areas of the synthesized powders are in the range of 130 and 163meter squaredg. High-resolution transmission electron microscopic TEM characterization showed that the particle sizes for the ceria materials are in the range of 3 and 10 nm. X-ray diffraction XRD and X-ray photoelectron spectra show the presence of transition metal oxide in the as prepared catalysts. The catalysts also test for water-gas-shift WGA reaction.
