Biosynthesis of copper(II) oxide nanoparticles using Murayya koeniggi aqueous leaf extract and its catalytic activity in 4-nitrophenol reduction

Copper(II) oxide nanoparticles (CuO NPs) have a wide range of applications as catalysts. The natural abundance of copper and its relatively low cost make it a viable alternative to catalysts that made from expensive precious metals such as platinum and palladium. In this study, a rapid, simple and g...
