Transformasi Katalis Birnessite Menjadi Cryptomelane Melalui Metode Pengendap…

The birnessite-type manganese oxide catalyst was synthesized by using the precipitation method by mixing reactants between KMnO4 and glucose with mole ratios of 3:1 and 2:3. The mixing reaction was carried out through three mixing methods, A (the KMnO4 solution was added dropwise to the glucose solution), B (the glucose solution was added dropwise to the KMnO4 solution), and the C method (the …
