Effectiveness of Ru/Mg/Ce supported on alumina catalyst for direct conversion of syngas to methane: Tailoring activity and physicochemical studies

The century of urbanisation and industrialisation had a great impact on the environment due to the rapid growth of the flue gas sectors. Thus, green technology is enforced to convert carbon dioxide (CO2) gas into methane (CH4) gas as an alternative fuel in electricity generation, particularly coal a...
