Photocatalytic degradation using metal nanoparticles is one of the most preferred method to eradicate water contamination mainly caused due to toxic azo dyes. In this study, synthesis of Copper nanoparticles(CuNP’s) is mainly discussed using aqueous extract of roots of Averrhoa carambola. Purpose of this study is to scientifically investigate photocatalytic efficacy of CuNP’s. Synthesised CuNP’s showed maximum wavelength at 278 nm after 30 minutes of synthesis. Fourier Tranform Infrared (FTIR) Spectroscopy results are obtained giving functional groups responsible in formation of CuNP’s. Field Emission Gun -Scanning Electron Microscopy (FEG-SEM) showed particle sizes in the range of 32.8 nm, 33.8 nm, 38.5 nm and 47.8 nm for CuNP’s .Whereas, Energy dispersive X-Ray spectroscopy (EDS) technique also determined presence and composition of synthesised CuNP’s formed. Futher , its photocatalytic efficacy is highlighted against degradation of Methyl orange. To summarise, in this study green CuNP’s proved to be an efficient nanocatalyst with 93.91 % degradation of methyl orange in six minutes.
