1：Experimental Design and Method Selection:

The study involved synthesizing ZnO nanorods via hydrothermal treatment and Ag nanoparticles via chemical reduction, then decorating ZnO with Ag nanoparticles at various concentrations (1-10%) to form nanocomposites. The photocatalytic performance was evaluated under UV light.

2：Sample Selection and Data Sources:

Methylene blue (MB) was used as the model dye. All reagents were analytical grade, purchased from Sigma-Aldrich and Daejung Chemicals.

3：List of Experimental Equipment and Materials:

Equipment included SEM (JEOL JSM-7500F), DLS (DynaPro NanoStar, Wyatt), Bio-AFM (NanoWizard II; JPK), XRD (Scintag-SDS 2000), UV-Vis spectroscopy (Alpha-1106), PL spectroscopy (Malvern Instruments), FT-IR (Nicolet 6700). Materials included AgNO3, NaBH4, NaOH, sodium citrate, CTAB, zinc acetate, ammonia solution, methanol, ethanol, and Milli-Q water.

4. Experimental Procedures and Operational Workflow: ZnO NRs were synthesized hydrothermally, Ag NPs were synthesized chemically, and nanocomposites were formed by mixing ZnO with Ag NPs in CTAB solution. Photocatalysis tests involved dissolving samples in MB solution, irradiating with UV light (365 nm), and measuring UV-Vis spectra at intervals.

5：Data Analysis Methods:

Data were analyzed using UV-Vis and PL spectroscopy to measure degradation rates and photocatalytic properties.
