In this work, a bibliometric study of POM-based photocatalysts publications was carried out with the help of VOSviewer and CiteSpace. The annual publication trend, prolific journals, geographical and institutional distribution, authors and their cooperation network, co-occurrence terminologies and reference co-citation network were analyzed. The results show that the publications on POM-based photocatalysts in the database date back to 1991, and the number of publications has increased rapidly since 2014. New Journal of Chemistry has been an active journal in recent years. Environmental Science & Technology has the highest citation frequency. Nine of the top 10 institutions in terms of the number of publications are from China, with Professor Wang Xiuli from Bohai University being the most prolific author. In addition, Northeast Normal University and Professor Wang Enbo have made outstanding contributions to the development of POM-based photocatalysts. Co-occurrence terminologies show that recent research focuses on carbon dioxide reduction and water splitting, and the reference co-citation network also confirms this trend.
