This study disclosed the aqueous immature fruits extract of Rubus coreanus act as a reducing and capping precursor for co-precipitation method in the synthesis Rubus coreanus zinc oxide nano particle (Rc-ZnO NPs). The development of Rc-ZnO was assured by white precipitated powder and analyzed by spectroscopic and analytical instruments. The UV-vis (UV-vis) studies indicate the maximum absorbance at 357 nm which confirmed the formation of ZnO NPs. Field emission transmission electron microscopy (FE-TEM), Fourier Transform Infrared (FTIR) and dynamic light scattering (DLS) showed the purity, functional group and monodispersity of ZnO NPs). The NPs is 23.16 run in size, crystalline in nature and possess hexagonal wurtzite structure and all this property were revealed by x-ray powder diffraction (XRD). The Rc-ZnO NPs were subjected for catalytic studies. The Malachite Green dye was degraded by Rc- ZnO NPs in both dark and light (indoor light) conditions and it degraded about 90% at 4 h' observation in both cases. The biodegradable, low cost Rc-ZnO NPs can be a better weapon for waste water treatment at day and night time for the safety of environment.
