Carbon-based materials, owing to their exceptional physicochemical properties, have significantly advanced developments in materials science, electronics, and energy sectors. Among these, graphene oxide (GO), a derivative of graphene that incorporates many oxygen-containing functional groups on its surface and edges, has garnered considerable scientific attention. Reduced graphene oxide (rGO), produced through the reduction of GO, offers enhanced electrical conductivity and surface area, thus providing substantial advantages across various scientific and technological fields. The rGO has found widespread application in sensor technologies, energy storage devices, electronics, and catalysis. Notably, in the field of environmental science, rGO-based materials present effective solutions for water purification, waste management, and pollutant detection and removal. In this study, a comprehensive bibliometric analysis was conducted using 72720 academic publications retrieved from the Web of Science (WOS) database, employing the R software for data analysis and visualization. The dataset comprised 65144 research articles, 5449 review articles, 1856 proceedings papers, 268 book chapters, and 3 books. Publications from 2001 to 2025 were evaluated based on publication trends, citation metrics, keywords, countries, journals, co-authors, and collaboration networks. This study systematically elucidates the research landscape of rGO in environmental applications, highlights emerging trends, and identifies potential directions for future investigations.
