The cryptomelane-type manganese oxide catalyst was synthesized using KMnO4 and glucose through a co-precipitation method with simultaneous mixing. The ratio of reactant concentrations of KMnO4 to glucose was 0.4M/0.6M; 0.2M/0.3M; 0.08M/0.12M; and 0.04M/0.06M. Characterization of the synthesized catalyst was conducted using X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), and Raman sp…
