A series of nickel foam supported cerai catalysts (ceria/NiF) for dry reforming of propane with carbon dioxide were prepared and their performance were evaluated at temperatures in the range of 520-600°C. Among the catalysts examined the 4 wt.% CeO2/NiF exhibited better low-temperature activity for the DRP, which is attributed to the formation of well- isolated nanosize CeO2 particles and highly reducible metal oxide species over the NiF support. The XPS and temperature programmed reduction (TPR) data also supported the incorporation of ceria into the NiO surface layer formed over NiF support, which was substantially higher in 4% CeO2/NF catalyst. Due to these favorable properties, the 4 wt.% CeO2/NiF could be considered as an excellent catalyst for DRP.
