Synthesis and characterization of binaryTiO2/AC nanocompositefor photocatalytic degradation for organic Congo Red dye removalemoval

Abstract

The synthesis, characterisation, and photocatalytic activity of titanium dioxide nanoparticles (ADT) doped with activated carbon and supported on environmentally activated carbon (PAC) have been covered in this work. Under visible light (496 nm), the photocatalytic activity of the nanocomposite was examined for the degradation of Congo Rd (CR) dye from aqueous solution. It was found that, for a 25 ppm CR solution, 100% degradation occurred in 90 minutes.This study used a UV-visible spectrometer to explore the photocatalytic degradation of Congo Red dye by TiO2/AC under UV irradiation. The obtained samples were characterized by X-ray diffraction (XRD), Field Emission-Scanning electron microscopy (FE-SEM), and Energy Dispersive X-ray dispersive spectroscopy (EDX). It also demonstrated that the Congo Red dye photocatalytic degradation reaction was fitted to a pseudo-first-order reaction. Findings indicated that CRD treatment.
