Facile synthesis of MnO2 nanoparticles for the removal of cationic dye

Abstract

MnO2 NPs were synthesized from Delonix elata leaves extract act as a capping and reducing agent by green synthesis process. The synthesized MnO2 NPs were characterized by different spectroscopic techniques such as IR, UV-Vis, SEM and XRD analyses. The UV spectrum of synthesized MnO2 NPs revealed optical properties at 340 nm. The XRD pattern of MnO2 NPs exhibited the crystallite size to be in the range of 20 nm and shows the amorphous structure. The morphological geographies of MnO2 NPs are spherical and faintly agglomerated. The FT-IR spectrum of MnO2 NPs spectacles stretching vibration of Mn–O at 510 cm−1 confirmed the formation of MnO2 NPs. MnO2 is superior photo degradation for methylene blue which is extant in the textile industries and it has an unlimited potential application in wastewater treatment.
