In-depth analysis on photocatalysts related research trends about polyoxometalate-based materials: A bibliometric study

In recent years, polyoxometalate-based materials have attracted wide attention in heterogeneous photocatalysis due to their various structure types and controllable redox properties. In this review, 1382 scientific publications related to polyoxometalate-based photocatalysts in the Web of Science database were investigated by a bibliometric method. The number of annual publications, journals, countries, institutions, authors, research hotspots, and references were analyzed. Through VOSviewer and CiteSpace software, the average publication time and citation frequency networks of journals, the cooperation network of different countries and institutions, the co-occurrence network of keywords, and the co-citation network of references were clustered and visualized to examine their contributions to related fields. The results could show the evolution of research hotspots in the past decades and provide reference and inspiration for researchers in polyoxometalate-based photocatalysis.
