To ensure the comprehensiveness and authority of the relevant literature, the scientific publication of POM-based materials in photocatalysis is retrieved from the SCI-Expanded in the Web of Science (Wos) Core Collection. The database contains high-quality literature information in many research fields such as natural science and engineering technology. In this work, we collect relevant literature through topic retrieval. The retrieval formula is as follows (TS=("polyoxometalate" OR "polyoxometalates" OR "polyoxometalates oxygen cluster" OR "metal-oxo cluster" OR "metal-oxygen cluster") AND TS=("photocatalytic" OR "photocatalysis" OR "photocatalyst" OR "light-driven catalyst")). The retrieved dataset was dated June 20, 2022, with a time interval from 1991 to 2021 (the first scientific publication in the database was published in 1991). The literature type is limited to "article" and "review". Finally, we obtained 1382 documents related to effective publications. It should be noted that the retrieval results will vary with time, as the database is constantly updated.
