Abstract
In this present study, we have reported a novel metal-free graphene oxide/graphitic carbon nitride (GO/g-C3N4) 2D/2D hybrid heterojunction for the removal of hazardous organic contaminants in aqueous solution under visible light embellishment. The reported photocatalyst was prepared by the combined ultrasonic dispersion method and thoroughly investigated by several spectral and microscopic studies viz FT-IR, p-XRD, SEM with EDX, TEM, XPS Photoluminescence etc., The photocatalytic activity of GO/g-C3N4 nanohybrids much outperformed than pristine g-C3N4 sample in the photodegradation of Rhodamine B and crystal violet organic pollutants. The enhanced synergistic effect of GO/g-C3N4 is mainly due to the proficient separation of photogenerated electron–hole pairs and tuned band gap with unique morphology. The major active species was determined by radical quenching experimental results with employing different scavengers. In this article, designates that the metal-free hybrid hetrojunction photocatalyst was a hopeful material in the waste-water control.
