The synthesis of metallic nanoparticles is an important and active area in nanotechnology. Green synthesis of metal nanoparticles is the easiest and environment-friendly methods, among which plant mediated synthesis has fascinated much consideration due to its simplicity, non-toxicity and also an inexpensive process. Different chemical and physical methods could be utilized for NPs synthesis. However, these methods are expensive and potentially hazardous for the living organisms and environment. Therefore, there is an essential need to develop an environmetally benign and low cost method of nanoparticles synthesis. Green Technology in which plant material used for synthesis of NPs is gaining a lot of interest. In the present review Copper oxide nanoparticles have been synthesized by bottom up approach using aqueous leaves extract of Neolamarckia <i>cadamba</i>. Plant extract acts as both reducing and capping agent. Nanoparticles were characterized by UV-Visible Spectrophotometer, FT-IR and XRD, SEM-EDX etc. The synthesized CuO NPs have been used as recyclable catalyst for organic transformation Knoevenagel Condensation reaction. Present synthetic reaction was very clean and high yielding for the synthesis of benzylidenemalanonitrile. Therefore, the study reveals the simplest method for the Green synthesis of CuO NPs.
