Abstract A metal-free combination of rGO/g-C 3 N 4 -coupled SrTiO (SRN) ternary nanocomposite prepared via a wet impregnation method for UV–Vis light photocatalytic applications. Various physicochemical properties the samples were investigated by several spectroscopic techniques including X-ray diffraction (XRD), FT-IR, Raman, field emission scanning electron microscopy with energy dispersive spectroscopy (FE-SEM-EDX), high-resolution transmission (HR-TEM), UV–Vis, photoluminescence (PL), photoelectron (XPS) and Brunauer–Emmett–Teller (BET) surface area analysis. The data suggest agglomerated SRT nanoparticles are dispersed distributed throughout rGO sheets GCN nanostructures. performance SRN towards combined mixed dye its degradation activities evaluated most common industrial effluents, Rhodamine B (RhB) Methylene blue (MB), under illumination. results revealed that efficiency photocatalyst shows excellent compared binary composition pure (SRT) sample. reaction rate constant RhB was estimated to be 0.0039 min −1 MB 0.0316 , which 3.26 4.21 (MB) times faster than enhanced attained not only interfacial formation but also speedy transportation electrons across heterojunction. After 5 runs recylic process, exhibited ultimate stability without structural changes, no noticeable observed. outcomes manifest dual scheme, enrichment could caused Z-scheme charge transfer process between GCN, SRT, nanocomposite, helps effectual separation keeps high redox potential. From results, sample provides insight into integration an effective potential wastewater treatment toward real-time environmental remediation
