Abstract:
In this study, the reported is environmentally friendly, cost-effective, and single-step procedure is
used for a successful green synthesis of cuprous oxide (Cu2O) by using prunus cerasifera plant
from a precursor salt, CuCl2.2H2O. Prunus cerasifera extract solution has contained Gallic acid,
which is a good capping or reducing agent for the reduction of dihydrated copper chloride to
Cu2O nanoparticle. The Cu2O nanoparticle was characterized by FT-IR spectroscopy and
powder XRD. The Nano sized cuprous dioxide (Cu2O) nanoparticles were used for the
photocatalytic reduction of hexavalent chromium. Hexavalent chromium Cr (VI) pollution makes
has a harmful impact on human health and the ecological environment. Photocatalysis reduction
technology exhibits low energy consumption, high reduction efficiency and stable performance,
and is playing an increasingly important role in chromium pollution control. Ultra violet cabinet
has been used to reduce Cr (VI) to the less harmful Cr (III) due to its visible light catalytic
activity, easily available, chemical stability and low cost photoreduction of hexavalent
chromium, Cr (VI), identified as carcinogenic and mutagenic element, to Cr (III), believed to be
an essential element, using cuprous dioxide (Cu2O) nanostructures as photocatalyst was
investigated under visible light irradiation. The reduction of Cr (VI) in aqueous solution by
visible light/ Cu2O was studied under various variables, pH, contact time and concentration of
hexavalent chromium.
