The CeO2 promoted Ni/CaFe2O4 catalyst was prepared using wet-impregnation technique. To ascertain the physicochemical properties, the as-prepared catalyst was characterized using various instrument techniques. The characterization of the catalysts reveals that CeO2-Ni/CaFe2O4 possesses suitable physicochemical properties for the conversion of methane (CH4) and carbon dioxide (CO2) to CO-rich H2. The thermo-catalytic reaction revealed that the CeO2 promoted Ni/CaFe2O4 catalyst displayed a higher CH4 and CO2 conversions of 90.04% and 91.2%, respectively, at a temperature of 1073 K compared to the unpromoted catalyst. The highest H2 and CO yields of 78% and 76%, respectively, were obtained over the CeO2-Ni/CaFe2O4 at 1073 K and CH4/CO2 ratio of 1. The CeO2 promoted Ni/CaFe2O4 catalyst remained stable throughout the 30 hours time on stream (TOS) while that of the unpromoted Ni/CaFe2O4 catalyst sharply decreased after 22 hours TOS. The characterization of the used catalysts confirms the evidence of carbon depositions on the unpromoted Ni/CaFe2O4 which is solely responsible for its deactivation. Whereas, there was a slightly gasifiable carbon deposited on the CeO2 promoted Ni/CaFe2O4 catalyst which could be ascribed to the interaction effect of the CeO2 promoter on the Ni/CaFe2O4 catalyst. � 2020 John Wiley & Sons Ltd Final 2023-05-29T08:09:07Z 2023-05-29T08:09:07Z 2020 Article 10.1002/er.5346 2-s2.0-85082965290 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85082965290&doi=10.1002%2fer.5346&partnerID=40&md5=46caf1c53d84cdb7e76322e4a05d6723 https://irepository.uniten.edu.my/handle/123456789/25413 44 8 6325 6337 All Open Access, Bronze John Wiley and Sons Ltd Scopus |
