In this study, the effects of adding CeO2 and La2O3 as promoters on the catalytic performance of Ni/Al2O3 catalyst were assessed.

The results revealed that the BET surface area of the synthesized catalyst slightly decreased when CeO2 and La2O3 were added due to the deposition on the porous structure of the support. Meanwhile, the XRD results demonstrated the increase in reducibility and dispersion of Ni using CeO2 promoter and the inhibited development of the non-active phase of Ni/Al2O3 using La2O3 promoter (i.e. NiAl2O4), resulting in the carbon formation and reduced efficiency of the catalyst. The catalytic performance in DRM at 800 °C showed that Ni/Al2O3-CeO2 catalyst exhibited higher catalytic performance in terms of CH4 and CO2 conversion with 89.6% and 91.2% respectively.
