چکیده

CeCuO3 nanoparticles with diameter 4.36 nm was synthesized by a fast and simple
microwave method using cerric sulphate tetra hydrate and copper sulphate pentahydrate as
starting reagents. CeCuO3 was synthesized under microwave heating for 6 min without calcining
steps. The synthesized products were characterized by X-ray powder diffraction (XRD) and
scanning electron microscopy (SEM) and the photocatalytic behaviour of nanosized CeCuO3 was
also studied spectrophotometrically through decolorization of yellowish orange and fast green
dyes, a prompt water pollutant from textile industries. The effect of variation of different
parameters i.e. pH, amount of CeCuO3, concentration of dye and light intensity was observed on
the rate of photocatalytic bleaching. A Tentative mechanism for the photocatalytic bleaching of
dyes has been proposed.
