Abstract

Nano-porous amorphous MnO2 was synthesized using sonochemical (sonication) and non-sonochemical (hydrothermal) processes to a 0.1 M KMnO4 solution with modified surface of silica and silica-alumina catalyst at room temperatures and 100⁰C respectively. Nano-porous amorphous MnO2 obtained was then characterized using infrared spectrometer (FT-IR), and the spectrum shows the absorption of MnO2 bonding. Structure of the product was later characterized by X-ray diffraction (XRD), and morphology scanned using a scanning electron microscope-variable pressure (VP-SEM) and transmission electron microscopy (TEM). The electrochemical behavior of MnO2 was studied and it shows reversible of MnO2 / Mn2+.
