Description
Summary:Using the sol-immobilization process with sodium borate as a reducing agent, a monometallic nanocomposite of platinum nanoparticles based on reduced graphene oxide was created in this study. Sunlight and a nanocomposite (Pt/rGO) were used as a photocatalyst to destroy the Rhodamine B dye, and the complete destruction of the dye took 240 minutes. The activity of the photocatalyst is evaluated by considering three parameters: 1) the amount of catalyst, 2) the pH, and 3) the initial rhodamine B concentration. The various photocatalysts were synthesized and their optical properties successfully characterized by Fourier transform infrared spectroscopy (FTIR), Raman, field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and UV-Visible spectrophotometers (UV-Vis) techniques. The outcomes demonstrated that Pt nanoparticles were evenly dispersed across the rGO surface. By utilizing 20 mg of catalyst at pH 7 and 10 ppm the concentration of the dye, complete destruction of RhB took place after 4 h, and roughly 98.8% of Rhodamine B was degraded through photocatalytic means.
