Ficus-mediated green synthesis of manganese oxide nanoparticles for adsorptive removal of malachite green from surface water.

The extract of ficus leaves was used to prepare manganese (IV) oxide nanoparticles (MnO NPs) for the first time. Several different analytical techniques were used to characterize the prepared MnO NPs. MnO has spherical crystals that are ~ 7 nm on average in size and have 149.
