The carbon dioxide dry reforming of methane (CDR) reaction could be thermodynamically favored inthe range of 800 to 1,000 oC. However, the catalyst in this reaction should be avoided at the calcination temperatureover 800 oC since strong metal support interaction (SMSI) in this temperature range can decrease activity due to lossof active sites. Therefore, we focused on optimizing the temperature of pretreatment and a comparison of surface characterizationresults for CDR. Results related to metal sintering over support, re-dispersion by changing of particle size ofmetal-support, and strong metal support interaction were observed and confirmed in this work. In our conclusion, optimumcalcination temperature for a preparation of catalyst was proposed that 400 oC showed a higher and more stablecatalytic activity without changing of support characteristics.
