METHODOLOGICAL INFORMATION

Description of methods used for collection/generation of data: https://doi.org/10.1016/j.seppur.2025.132950

Methods for processing the data: Selection of data obtained from the experimental instrument in CSV format or scanning imagens in tiff format. In the case of tables 1, 2 and S-1 the data are obtained after measurements of Hydroxyl radical generation was monitored by the N,N-dimethyl-p-nitroaniline (RNO) disappearance, by determining the triiodide concentration produced during the reaction of persulfate generated during the electrolysis with an iodide excess, hydrogen peroxide formation was determined using spectrophotometric kits (0.0156.00 mg/l H2O2 Spectroquant) (Supelco) and determined with a Prove 100 Spectrophotometer (Merck) and ozonegeneration was determined using the APHA Method 4500-O3. In the case of tables 3 and 4 the data are obtained after analysis of Total Organic Carbon and non-purgeable organic carbon, by Shimadzu TOC-VCSN analyzer, Chemical Oxigen Demand by a digester apparatus (Spectroquant TR320) and a test analyzer (Spectroquant NOVA),percentage of degradation by fluorescence by fluorescence spectroscopy determination of NPs concentration in the different samples was carried out using a Photon Technology International spectrofluorometer, employing an excitation wavelength of 230 nm and an emission range of 260600 nm  and the electrical energy consumption per order (EEO) were calculated using formulas used in bibliography.  

Software: Microsoft Excel 2021.

Environmental/experimental conditions: room temperature (electrochemical experiences and fluorescence d FTIR-ATR spectroscopy) or ultra-vacuum (TEM and FESEM).
