For the purpose of developing a novel and effective nano-CeO2 catalyst used in biomass gasification for tar removal, nanocrystalline CeO 2 particles were successfully prepared by the homogeneous precipitation method, and different approaches including TG, FT-IR, XRD and SEM were used to characterize the CeO2 nano-particles and precursors in this study. The analysis results indicated that the synthesized precursor was hydrated cerium basic carbonates and its formula was identified as Ce 2O(CO3)2 nH2O, and it can completely transform into nanocrystalline CeO2 particles below 400 °C under the...
