Facile synthesis of MnO2 nanoparticles for the removal of cationic dye

Abstract MnO 2 NPs were synthesized from Delonix elata leaves extract act as a capping and reducing agent by green synthesis process. The synthesized MnO 2 NPs were characterized by different spectroscopic techniques such as IR, UV-Vis, SEM and XRD analyses. The UV spectrum of synthesized MnO 2 NPs revealed optical properties at 340 nm. The XRD pattern of MnO 2 NPs exhibited the crystallite size to be in the range of 20 nm and shows the amorphous structure. The morphological geographies of MnO 2 NPs are spherical and faintly agglomerated. The FT-IR spectrum of MnO 2 NPs spectacles stretching vibration of Mn–O at 510 cm −1 confirmed the formation of MnO 2 NPs. MnO 2 is superior photo degradation for methylene blue which is extant in the textile industries and it has an unlimited potential application in wastewater treatment.
