1：Experimental Design and Method Selection:

The study involved the synthesis of LaZF@rGO nanohybrids via a hydrothermal-induced precipitation process. The photocatalytic performance was evaluated under UV irradiation with the aid of peroxydisulfate.

2：Sample Selection and Data Sources:

Rhodamine B (RhB) was selected as the target pollutant. The study also evaluated the removal of a wide spectrum of organic contaminants.

3：List of Experimental Equipment and Materials:

Equipment included a UV-Vis spectrophotometer, X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and a vibrating sample magnetometer (VSM). Materials included natural graphite, RhB, zinc nitrate hexahydrate, iron(III) nitrate nonahydrate, lanthanum(III) nitrate hexahydrate, and potassium peroxydisulfate.

4：Experimental Procedures and Operational Workflow:

The synthesis of LaZF@rGO involved a hydrothermal-induced precipitation method. Photocatalytic experiments were conducted under UV irradiation with varying conditions such as pH, initial dye concentration, and PDS concentration.

5：Data Analysis Methods:

The photocatalytic activity was analyzed using pseudo-first-order reaction kinetic constants. The structural, optical, and physicochemical properties of the synthesized photocatalyst were characterized using various analytical techniques.
