1：Experimental Design and Method Selection:

The study employed an evaporation induced self-assembly (EISA) method combined with molecular imprinting technique to fabricate MI-meso-TiO2 photoanodes. PEC oxidation experiments were conducted with a bias potential to enhance charge separation.

2：Sample Selection and Data Sources:

Atrazine was used as the target contaminant, with comparisons to hexazinone and 2,4-D. Real water samples from a sewage treatment plant were spiked with atrazine for complex system tests.

3：List of Experimental Equipment and Materials:

Equipment included FE-SEM (Hitachi S-4800), HR-TEM (JEM 2100), XRD (Bruker D8 Advance), N2 adsorption analyzer (Micromeritics TriStar 3020), UV-Vis spectrophotometers (AvaLight-DHS, Agilent 8453), FT-IR (Nicolet 8700), Raman microscope (inVia reflex), fluorescence spectrometer (JY Fluorolog-3-Tou), HPLC (Agilent 1260), LC-MS (Varian 310), and a PEC cell with a Xe lamp (PLS-SXE300). Materials included Pluronic P123, atrazine, tetraethyl orthotitanate, and other chemicals.

4：0). Materials included Pluronic P123, atrazine, tetraethyl orthotitanate, and other chemicals. Experimental Procedures and Operational Workflow:

4. Experimental Procedures and Operational Workflow: MI-meso-TiO2 was prepared by sol-gel method, calcined, and used as anode in PEC degradation experiments. Adsorption studies, fluorescence lifetime measurements, hydroxyl radical quantification, and in situ ATR-FTIR were performed.

5：Data Analysis Methods:

Kinetics followed pseudo-first-order models; data were analyzed using HPLC and LC-MS for degradation products, with statistical methods for rate constants and activation energies.
