Both Co3O4 (with crystal size: 5.2�8.4 nm) and La2O3 nanoparticles were finely dispersed on support surface. The promotional La2O3 effect could noticeably increase CH4 and CO2 conversions to 29.3% and 17.3%, correspondingly due to improved basic site concentration and decreasing crystallite size of active metal in association with promoter addition. 5%La loading was an optimal promoter content for reactant conversions as well as yield of H2 and CO. 5%La-10%Co/Al2O3 also exhibited the highest resistance to carbon deposition owing to the basic nature, redox feature and oxygen vacancy of La2O3 dopant. Notably, the H2/CO ratio obtained within 0.84�0.98 is preferable for Fischer-Tropsch reaction in downstream to yield liquid hydrocarbon fuels. � 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
