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).
