This archive contains all raw measurement data that was used to create outputs for the scientific publication Inorg. Chem. 2025, 64, 36, 18166–18174 (https://doi.org/10.1021/acs.inorgchem.5c02157). Specifically, these are measured XRD, XPS, BET and UV-Vis and fluorescence spectroscopic data in ASCII XY format, images taken using TEM in .bmp format and kinetic data from measurements of photocatalytic degradation of bisphenol-S using HPLC in ASCII XY format. All measurements are given for three prepared samples, namely CeO2, Mo6 and the CeO2@Mo6 composite. The archive also contains a readme.txt file that contains specific measurement details for individual methods and electronic supporting information with additional measurements, which were supplemeted to the original article. The structure of the folders is as follows: GA25-15972S/2025/ INORG_CHEM_10.1021/acs.inorgchem.5c02157/DATA_TYPE(ANALYTICAL_METHOD)/ SAMPLEID_ADDITIONAL_INFO.* Naming of the files: SAMPLEID_ADDITIONAL_INFO.*
