    Graphene Oxide Research: Current Developments and Future Directions by Meiqiu Zhan, Minjie Xu, Weijun Lin, Haijie He, Chuang He

    Published 2025-03-01
    “…This study bridges these gaps through a scientometric analysis of 14,124 peer-reviewed articles (2022–2025) from the Web of Science Core Collection, utilizing CiteSpace for co-occurrence network mapping, burst detection, and cluster analysis. Key findings reveal (1) a thematic shift from traditional synthesis optimization (e.g., Hummers’ method) toward driven material design and sustainable applications like GO membranes for water purification; (2) China’s dominance in publication output (38.5%) contrasts with the U.S. and Europe’s leadership in global collaborations; (3) interdisciplinary journals such as <i>Chemical Engineering Journal</i> (centrality: 0.25) and emerging clusters like “circular economy” signal transformative priorities; and (4) critical gaps in scalability, ecological safety, and cost-effective production hinder industrial translation. …”
