Bio-molecule capped α -MnO _2 nanoparticles have been successfully synthesized from the reduction of KMnO _4 via a facile green synthesis route using an aqueous leaf extract of Bryophyllum pinnatum as a reducing and capping agent. The synthesized α -MnO _2 nanoparticles were characterized by x-ray diffraction (XRD), Fourier transform—infrared (FT-IR), energy dispersive x-ray (EDX), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), thermogravimetric (TG) and differential scanning calorimetry (DSC) techniques. Experimental results clearly demonstrate the successful synthesis of bio-molecule capped crystalline tetragonal α -MnO _2 nanoparticles with the size of 4–18 nm. The magnetic property of the product was evaluated using a vibrating sample magnetometer (VSM) and the result reveals that the presently synthesized bio-molecule capped α -MnO _2 nanoparticles exhibit ferromagnetic property at room temperature.
