Synergistic adsorption-photocatalysis <i>via</i> rGO-mediated electron shuttling in ultrasonically synthesized NiO/g-C₃N₄-based ternary nanocomposites for Safranin O removal.

ABSTRACT: This study reports the facile ultrasound-assisted synthesis of a ternary rGO/NiO/g-C₃N₄ nanohybrid (rGO-GN10) for efficient safranin O (SAF) removal via synergistic adsorption and photocatalysis. The composite was strategically engineered to transcend the limitations of binary systems by establishing an rGO-bridged direct Z-scheme heterojunction, which not only achieves exceptional charge separation but also uniquely synergizes multi-mechanistic adsorption with photocatalytic mineralization at the shared interface. Advanced characterization confirmed successful integration: XRD identified crystalline NiO and g-C₃N₄ phases, while HRTEM revealed hierarchical heterostructures with intimate interfacial contact enabling efficient charge
