A short review on informetric analysis and recent progress on contribution of ceria in Ni-based catalysts for enhanced catalytic CO methanation

Energy demand is rising, and the exhaustion of accessible energy sources is currently the greatest challenge. CO methanation has become a crucial reaction for the substituted natural gas production, necessitating a catalyst. Ceria is amongst the most extensively utilized metal oxides owing to its abundance of oxygen vacancies. Despite substantial study on CO methanation, no paper evaluates the impact of ceria in Ni-based catalysts for CO methanation. Hence, we have provided a bibliographic analysis and recent progress on contribution of ceria in Ni-based catalysts for enhanced catalytic CO methanation. This article shows the findings of an informetric investigation of CO methanation conducted between year 1970 and 2022 by examining data from 156 sources and 585 publications. Information regarding the relationships amongst keywords, countries, and journals, an intercountry co-authorship network analysis, and a conception of the co-occurrence network were supplied. Our review concludes with technical challenges and suggestions for future research.
