Synthesis of g-C3N4/CoFe2O4 Composite for Photocatalytic Degradation of Methylene blue in Aqueous Solution

Abstract

Herein, in this study, we have reported a successful synthesis of g-C3N4, CoFe2O4 Nps and g C3N4/CoFe2O4 nanocomposite materials for photocatalytic degradation of methylene blue dye. Direct calcination of urea at 550 oC for 3 h was employed to synthesize g-C3N4, CoFe2O4 and synthesized using a facile co- precipitation method. Besides, g-C3N4/CoFe2O4 nanocomposite was synthesized by a simple co-precipitation method. The crystalline structure, functional group presents and surface charge of the synthesized photo catalysts was investigated by powder XRD, FTIR and pHpzc techniques respectively. The XRD analyses show the formation of the desired phases of g-C3N4, CoFe2O4 NPs and g-C3N4/CoFe2O4 composites. The photocatalytic efficiency of the synthesized semiconductor materials were investigated by the degradation of MB. Among the synthesized nonmaterial’s, g-C3N4/CoFe2O4 shows maximum photocatalytic efficiency than the other which is due to lowering the band gap and effectively reduces the recombination rate of electron-hole pairs during the photocatalytic reaction. The photocatalytic activities were investigated at varying pH of solution, contact time (min), initial concentration of MB (mg/L), and photocatalyst dose (mg).
