Sintesis Mangan Oksida Dengan Metode Pengendapan Dan Aplikasinya Untuk Degrad…

Manganese oxide cryptomelane-type Octahedral Molecular Sieve (OMS) was synthesized by the reaction between KMnO4 and C6H8O7 (citric acid) with a mole ratio of 5:1 using precipitation method. The effect of citric acid flow rates (1, 2, and 3 mL/minutes) on the synthesis of MnO2 was studied and correlated with its catalytic activities. The as-synthesized manganese oxides were then characteri…
