1：Experimental Design and Method Selection:

A facile in-situ solvothermal method was used to synthesize Ag/Bi/BiOCl heterojunction photocatalysts with varying AgNO3 content to regulate Bi incorporation and oxygen vacancies.

2：Sample Selection and Data Sources:

Samples were prepared with different amounts of AgNO3 (0,

3：01, 1, 2 mmol) and characterized using various techniques. List of Experimental Equipment and Materials:

Materials included AgNO3, glycerol, CTAC, Bi(NO3)3·5H2O, deionized water. Equipment included XRD (Bruker D8 Advance), FE-SEM (Hitachi S-4800 N), TEM (SU-8010), HRTEM (Tecnai F30 FEI), XPS (Thermo ESCALAB 250XI), UV-Vis-NIR spectrophotometer (UV-3100, Shimadzu), BET analyzer (Quantachrome Autosorb-iQ), PL spectrophotometer (Lumina, ThermoFisher), photocatalytic reactor with Xenon lamp (CEL-HXF300), and UV-vis spectrometer (Shimadzu UV-2550).

4：0). Experimental Procedures and Operational Workflow:

4. Experimental Procedures and Operational Workflow: Precursors were dissolved, mixed, stirred, heated hydrothermally at 180°C for 5h, washed, dried, and characterized. Photocatalytic tests involved degrading RhB under UV, visible, and NIR light with samples stirred in dark for equilibrium before irradiation.

5：Data Analysis Methods:

XRD for phase identification, SEM/TEM for morphology, XPS for chemical states, BET for surface area, UV-Vis-NIR for optical properties, PL for charge separation, and kinetic analysis using pseudo-first-order model for degradation rates.
