The biosynthesis of nanoparticles put forward a cost-free and eco-friendly method for the synthesis of nanoparticles. In this paper degradation of Malachite green has been carried out using Copper nanoparticles synthesized by Aloe Barbadensis leaf extracts. The green synthesis of the copper nanoparticles has been carried out using an aqueous solution of copper sulphate and extract of Aloe Barbadensis. The colour change of the reaction mixture containing 1mm copper sulphate has been observed from deep blue to colourless and then brick red to dark red indicating the formation of copper nanoparticles. For the characterization of CuO nanoparticles, Ultraviolet (UV), Infrared (IR), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) have been used. The experimental analysis has revealed an average 60n sized synthesized CuO nanoparticles. The shape of copper nanoparticles has been observed as spherical and cubic ranging between 80-120nm. The different functional group of synthesized nanoparticles has been examined usingFourier-Transform Infrared Spectroscopy (FTIR). The UV spectrophotometer has confirmedthe peak of Copper nanoparticles at 265-285nm.The maximum absorbance of Copper oxide nanoparticles has been observed at 280nm. copper oxide /zinc oxide nanocomposite were synthesized using cheap and cost effective sol-gel method. These cuo/zno nanocomposite were characterized by analytical techniques like (SEM), (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-VIS. The Fourier transform IR analysis result confirmed that composite material were formed. SEM images showed the particle size in the range between 15 to 35nm. Nanocomposite exhibited excellent microwave induced catalytic degradation for malachite green (MG) dye. The initial concentration was 1.8 X 10-5M degradation. The microwave induced catalysis reaction gained about 80% degradation of Malachite Green dye.To know more click on below link.
