The effect of preparation condition on the performance of Ni-based catalysts was investigated for the glycerol steam reforming. The La0.7Ce0.3NiO3 mixed oxides were synthesized using different solution concentrations and calcination temperatures by co-precipitation method. BET, ICP, XRD, TPR, FE-SEM, CO2-TPD, TGA and Raman spectroscopy were used to characterize the catalysts. Including La2NiO4 phase at lowest solution concentration, catalyst precursor included LaNiO3 phase instead of La2NiO4 at other solution concentrations. At low calcination temperature of 700 C, it was found that smaller particle size of CeO2 incorporated more lanthanum, higher surface basicity and La2O2CO3 phase could effectively inhibit and eliminate coking leading to the better performance of catalyst.
