1：Experimental Design and Method Selection:

The study employed a gaseous bubble templating approach using ammonium lauryl sulfate (ALS) to synthesize worm-like porous g-C3N4. The rationale was to create a porous structure for improved surface area and photocatalytic activity. Theoretical models include bandgap energy calculations and charge carrier dynamics.

2. Sample Selection and Data Sources: Samples were synthesized with different mass ratios of ALS to melamine (1%, 2%, 4%). Bulk g-C3N4 was prepared as a control. Data sources include characterization techniques like XRD, UV-vis DRS, SEM, TEM, FTIR, XPS, BET, PL, EPR, and photocatalytic degradation tests.

3：List of Experimental Equipment and Materials:

Materials included melamine (C3H6N6) and ammonium lauryl sulfate (ALS) from Aladdin Chemical Reagent Corp., DI water. Equipment: Rigaku D/MAX 2550 VB/PC for XRD, Varian Cary 500 UV-vis spectrophotometer, Nova Nano SEM 450 SEM, JEM2000EX TEM, Nicolet Magna 550 FTIR spectrometer, PerkinElmer PHI 5000C ESCA XPS system, ASAP2020 BET analyzer, Shimadzu RF-5301 spectrofluorophotometer for PL, FLSP920 Edinburgh Fluorescence Spectrometer for time-resolved PL, Bruker EMX Plus-10/12 EPR spectrometer, 300 W Xe lamp with cutoff filter for photocatalytic tests, UV-vis spectrophotometer for RhB concentration, Agilent 1260 HPLC for phenol concentration.

4：Experimental Procedures and Operational Workflow:

Synthesis involved dissolving ALS in water, adding melamine, stirring at 80°C to dry, milling, heating at 520°C for 2h, then 600°C for 3h. Photocatalytic tests: 50 mL of RhB or phenol solution with catalyst, dark stirring for 0.5h for adsorption equilibrium, irradiation with Xe lamp, sampling at intervals, centrifugation, and concentration measurement.
