Abstract
A user friendly one step calcination method was used for synthesis of cobalt oxide-graphitic
carbon nitride nanocomposite for the present study. The precursor used here for
graphitic carbon nitride is abundantly available urea. The synthesised samples were
characterised by X-ray diffraction (XRD), Field emission scanning electron microscope
(FESEM) and Energy dispersive X-ray (EDX). The presence of cobalt oxide was confirmed
by EDX. The flower like morphology was observed in FESEM. The XRD confirmed the
crystalline nature of the nanocomposite.
The photocatalytic degradation of Azure B was observed under visible light using
synthesized nanocomposite as photocatalyst. The various parameters like pH, concentration
of dye, amount of composite and intensity of light were also observed. The present
investigation showed the increased photocatalytic activity of nanocomposite as compared
to g-C3N4 and cobalt oxide alone.
