In this study, we failed to collect all the literature related to POM-based photocatalysts due to the limitations of the literature database and retrieval formulas. However, this can provide a more objective perspective for the evolution of POM-based photocatalysts research hotspots. There are indeed some limitations in the quantitative analysis of publications through bibliometrics. For example, a researcher's influence cannot be judged simply by the number of papers published by the author. To eliminate these shortcomings as far as possible, we introduced TC and AC evaluation indicators. In addition, it is unreasonable to blindly identify a paper with low research value in the reference analysis and co-citation network because there is no high citation frequency. The number of citations is a dynamic indicator that increases over time.
