Green synthesis of nanoparticles is emerging trend in present scenario for development of new material. Chromium nanoparticles (Cr Nps) have been synthesized by green technique from peel extracts of selected two plants.viz Pisum Sativum and Citrus lemon peels. Such synthesized nanoparticles have been characterized and used for the degradation of dyes and also compared for antibacterial activity. Energy efficiency, minimal toxicity, high yields, economic effectiveness, and easy accessibility are few benefits of synthesized Cr NPs. Nano particles were characterized by using scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy, and X-ray diffraction and size was confirmed in the range of 30 to40 nm. Such synthesized particles have shown potential of photocatalytic activity as well as antibacterial nature
