1：Experimental Design and Method Selection:

The study designed a Fenton-PFC system with dual rotating electrodes to enhance oxygen transfer and active species generation. It utilized TiO2 nanotubes as the photoanode and (NH4)3PO4 modified bamboo charcoal as the cathode catalyst. The rationale was to combine photocatalysis and Fenton processes for efficient organic degradation and electricity production.

2：Sample Selection and Data Sources:

Methyl orange (MO) was used as the probe organic pollutant. Solutions were prepared with specified concentrations of MO, Na2SO4, and FeSO4. Data on degradation, H2O2 concentration, COD, and current were collected during experiments.

3. List of Experimental Equipment and Materials: Equipment included a semicircular quartz reactor, motor device for rotation, xenon lamp for UV irradiation, SEM for morphology analysis, XPS for surface composition, UV-VIS spectrophotometer for concentration measurements, COD detector, and data acquisition system for current and voltage. Materials included titanium plates, bamboo charcoal, chemicals like methyl orange, ethylene glycol, Na2SO4, FeSO4, NH4F, (NH4)3PO4, p-benzoquinone, and Nafion emulsion.

4：Experimental Procedures and Operational Workflow:

The TiO2 photoanode was prepared by anodic oxidation and annealing. The BC cathode was fabricated by loading modified BC particles on a titanium plate. Experiments were conducted in the reactor with electrodes rotated at specified speeds. MO degradation was monitored over time under UV irradiation, with parameters like pH, Fe2+ concentration, BC loading, and rotation speed varied. H2O2 concentration and COD were measured periodically.

5：Data Analysis Methods:

Data were analyzed using pseudo-first-order kinetics for degradation rates. XPS spectra were deconvoluted to identify functional groups. Energy consumption and power output were calculated based on experimental measurements. Statistical analysis involved repeating experiments three times.
