Data and code supporting the study of photocatalytic transformation of 2,4-D by copper-modified tungstophosphoric acid supported on natural zeolite DANIEL HORACIO MENDOZA CAMARENA (25074094) YAIR CRUZ-NARVÁEZ (25074109) DAVID CORREA COYAC (25074110) JOSÉ JAVIER CASTRO ARELLANO (25074113) ISAÍAS HERNÁNDEZ PÉREZ (25074115) Materials engineering not elsewhere classified Computational chemistry Inorganic green chemistry Analytical chemistry not elsewhere classified 2,4-D photocatalysis tungstophosphoric acid natural zeolite copper-modified catalyst FT-ICR MS HPLC polyoxometalate density functional theory mass spectrometry <p dir="ltr">This dataset and code package supports the study of the photocatalytic transformation of 2,4-D by copper-modified tungstophosphoric acid supported on natural zeolite. It contains processed HPLC data supporting the reported decrease in the integrated peak area of parent 2,4-D, processed FT-ICR MS data and derived evidence tables used for confidence-ranked composition/family assignments and harmonic-artifact assessment, material-characterization data, and computational chemistry inputs, outputs and derived datasets supporting the reported electronic-structure and polyoxometalate analyses. The package also includes historical analysis code, provenance records, metadata, SHA-256 manifests and documentation of analytical limitations. The deposited materials support parent-compound disappearance and bounded MS/computational interpretations; they should not be interpreted as evidence of complete mineralization, complete detoxification, or unambiguous structural identification of all FT-ICR candidate species. Version 1.1 incorporates recovered historical FT-ICR audit code and corrected executable-provenance documentation without altering the underlying scientific data or reported analytical results.</p><p><br></p><p dir="ltr">Version 1.2 adds the reproducible derived authority for the three tracked HPLC chromatographic signals across the reaction series. FT-ICR MS, material-characterization and computational scientific datasets are unchanged.</p> 2026-10-06T23:13:51Z Dataset Dataset 10.6084/m9.figshare.33940900.v2 https://figshare.com/articles/dataset/Data_and_code_supporting_the_study_of_photocatalytic_transformation_of_2_4-D_by_copper-modified_tungstophosphoric_acid_supported_on_natural_zeolite/33940900 CC BY 4.0
