Author cooperation network analysis can indicate the propensity of researchers in a given discipline to collaborate, guiding researchers eager to seek collaboration. In addition, it is a valuable measure for examining the best collaborations in the field. POM-based photocatalysis has attracted strong interest from researchers. The 1382 scientific publications related to POM-based photocatalysis came from 4195 authors. These authors are the contributors in this field, especially those with a high number of publications. The number of authors who published one paper was 3066 (73 per cent of the total), and the number of authors who published two papers in collaborative papers was 544 (12.8 per cent). From the author's output dimension, most authors produced a small number of papers in the study of POM-based photocatalysis, while a few authors produced outstanding results in this study. We removed data with low research significance to avoid too many nodes and connections leading to blurred visualization results. The visualization threshold is defined as 4, which means that the authors who publish less than four articles will not appear in the clustering visualization results. Finally, the VOSviewer software is used to visualize the author cooperation network, and 355 nodes are obtained. Figure It is one-sided to evaluate the contribution and ability of a scientific researcher only by the number of scientific publications. The number of citations of the author's literature is also an evaluation index that cannot be ignored. The density of citation times of these high-yield authors is shown in Figure . Each node corresponds to an author. If the centre colour of a node is more profound, it means that the author's article has a higher number of citations. The total number of citations of Wang Enbo (2276 times), Li Yangguang (2063 times), Ding Yong (1632 times) and Su Zhongmin (1552 times) exceeds 1500 times, which is a high-yield and highly cited scholar in this field. The work of highly cited scholars has a high degree of recognition in POM-based photocatalysts, and their papers are pioneering.
