Abstract

Green routes of synthesis are simple, safe, nontoxic and eco-friendly methods to synthesize nanoparticles of various metals and their oxides by the application of bioactive compounds of plants, algae, fungi, yeast, etc. Green engineered copper and copper oxide nanoparticles (Cu and CuO NPs) synthesis has been reported to be more economical and best alternative method among available methods. Cu and CuO NPs have been applied as dietary additives, lubricant supplements, chemical sensors, coating materials in addition to large number of biotechnological and pharmaceuticals applications. The present review aims to bring awareness about various aspects of biogenic synthesis of Cu and its oxide NPs for multifunctional applications and discusses their characterization techniques and applications in antimicrobial activity evaluation, photocatalysis, organic dye degradation, biomedical, pharmaceutical, cosmetic, energy and catalysis. The photo catalytic performance of the synthesized nano-crystalline Ag₂O by photocatalytic degradation of organic dyes under visible light irradiation has also been discussed thoroughly in this review.
