In this study, Bentonite-Ag3PO4 (BAP) material was synthesized via the co-precipitation method, and its photocatalytic activity was evaluated for the degradation of Rhodamine B (RhB) at a concentration of 10 mg/L in a 300 mL solution under simulated UV irradiation. The synthesized material was characterized using various techniques, including X-ray diffraction, Fourier-transform infrared spectrometry, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM–EDS), UV–Vis diffuse reflectance spectroscopy (DRS), and Brunauer– Emmett–Teller (BET) surface area analysis. The photocatalytic activity of BAP at a concentration of 1 g/L exhibited excellent performance, achieving 100% degradation of RhB after 90 minu under simulated UV365 nm irradiation. The charge carrier pathway was investigated using scavengers for photogenerated holes ( h+), hydroxyl radicals ( HO⋅), and superoxide radicals ( O⋅− 2 ), such as ethylenediaminetetraacetic acid (EDTA), isopropanol (IPA), and benzoquinone (BQ).
