ABSTRACT The research examines the green production along with characterizations and photocatalytic evaluation of Ag/g‐C 3 N 4 nanocomposites through the Sapindus emarginatus fruit extract as a biologically sourced reduction and stabilization agent. X‐ray diffraction (XRD), SEM, TEM, EDAX, BET, and UV–vis spectroscopy were applied to study the nanocomposites. The nanocrystalline state combined with a uniform surface and increased specific surface area along with optical band gap shift toward red light makes absorption of visible light possible. Under visible light exposure the MO dye photodegraded to achieve more than 98% degradation efficiency within 75 min. Silver doping enhances the performance of the material by forming plasmonic resonance, as well as, the separation of carrier charges. The scavenger tests showed the core reactive varieties hydroxyl radicals (OH), photo‐generated holes (h + ) and superoxide radicals ( . O 2 ) which are also involved in the photocatalytic degradation process. The nanocomposite displayed stable performance as a catalyst for various cycles which demonstrated its durability together with reusability properties. The research indicates that environmentally friendly synthesized Ag/g‐C 3 N 4 nanocomposites demonstrate potential for restoring polluted areas including wastewater treatment facilities.
