In this research, Fe2O3 nanoparticles inside of mesoporous tube support SBA-15 (Fe2O3@SBA-15) was synthesized by sol-gel method and used to generate syngas from methane. Some techniques were used to characterize the material, including XRD, BET, TEM, SEM, and TGA. As oxygen carriers for methane partial oxidation, this material can reach up to 99% syngas selectivity in TGA tests. Bulk Fe2O3 and Fe2O3 nanoparticles on SBA-15 were also synthesized and compared with Fe2O3@SBA-15. Experiment results showed that nanoparticles inside of the silica tubes are the key to high selectivity of the reaction. The mechanism of Fe2O3@SBA-15 as a good performance oxygen carrier was also discussed.
