This work used VOSviewer to conduct bibliometric studies on the Scopus database to examine scientific trends in metal oxide oxidation-reduction processes for energy storage systems. This study is supplemented by a literature assessment of the most recent theoretical breakthroughs in iron-based catalysis for hydrogen production and energy storage systems. 1980 related research documents were collected and selected from the Scopus database based on the results of harvesting research documents on related topics using the keywords “iron,”“hydrogen,”“energy,” and “oxide” using Publish or Perish in the last ten years (2014–2023). According to data analysis for the last ten years, publications on connected keywords increased in 2016–2022 from 106 to 332 articles and declined in 2023 to 169 publications. Three types of analysis visualization on the catch data are available to help this study: network visualization, overlay visualization, and density visualization. The findings of this study could help academics identify global research trends relating to the proposed keywords, which may then be utilized as a reference in future research.
