Synthesis and support composition effects on CH4 partial oxidation over Ni-CeLa oxides

- Ni supported over CeO2, La2O3 and mixed CeO2-La2O3 are active in CPO reaction.
- Co-precipitation produces smaller NiO and CeO2 crystallites as compared to wet impregnation.
- Carbon deposition does not occur over the mixed oxide supported Ni catalysts.
- Deactivation is not related to coke.
- Carbon deposition prevents Ni sintering.
