Background:
In the recent years, the green synthesis of nanoparticles has taken a lead role over the conventional
chemical and physical approach due to its non-toxic, cost effective parameters and has found its place in various
applications.
Objectives:
The major objectives of this study was to synthesise and characterize the copper nanoparticles using the rose
extract at different set of conditions and analyse these nanoparticles as a source of dye degradation agent under sunlight
conditions.
Methods:
Present study was conducted with the aim to synthesis the copper nanoparticle using the rose petal extract. The
components present the in the extract act as the reduction and stabilization agents for the synthesis of CuNPs. The
synthesized nanoparticles were characterized by using UV-VIS, FTIR, XRD and SEM analysis. Photocatalytic degradation
of two dyes (Malachite Green and Carbol fuchsin) was analysed using double beam spectroscopic analysis
Results:
UV-Vis analysis indicated the presence of a peak at around 630 nm. The FT-IR analysis indicated the involvement
of various biomolecules during the synthesis of nanoparticles. The structure and the conformation was elucidated using
XRD and SEM showed the agglomerated form of the synthesized nanoparticles with the size range of about 60-90 nm. The
synthesised copper nanoparticles was used for degradation of malachite green and carbol fuchsin dye using photocatalytic
under sunlight irradiation. UV-Vis spectral analysis indicated that synthesised copper nanoparticle act more effective in
degradation of malachite green (around 95%) whereas carbol fuchsin showed a maximum degradation by 52% therefore
suggesting that CuNPs act as an efficient photo catalyst in dye degradation.
Conclusion:
The results obtained from this study indicates that rose extract has the potential of synthesis of copper
nanoparticles which is non-toxic and convenient approach as compared to physical and chemical synthesis. These
nanoparticles can be effectively employed as dye decolourization agents to treat industrial effluent and prevent the
environmental pollution.
