Sintesis Komposit Mno2/Mgo Dengan Metode Sol-Gel Dan Uji Aktivitas Katalitik Untuk Degradasi Metilen Biru

SUMMARY
Cryptomelane type manganase oxide is a tunnel manganese oxide with pore size of 2 x 2. Cryptomelane can be used as an adsorbent and catalyst for the degradation of waste organic compounds. Methylene blue (MB) is a dye that is difficult to be degraded naturally, therefore an effective method is needed to degrade the dye. Fenton-like method with Fenton heterogeneous composite MnO2/MgO catalyst was used to degrade methylene blue dye. In this study, MnO2/MgO composites were synthesized using a one-step sol-gel method by reacting KMnO4, glucose and MgO simultaneously. The as synthesized composites were characterized using X-Ray Diffraction (XRD), which indicated the formation of cryptomelane type manganese oxide and Fourier Transform Infra Red (FTIR) which indicated the presence of Mn-O and Mg-O functional groups. The synthesized MnO2/MgO composite was then applied for the degradation of methylene blue using H2O2 as oxidant. The optimum degradation of methylene blue was obtained under conditions of 60 ppm methylene blue concentration, 15 mL H2O2 volume and 25 mg composite mass which was able to degrade MB 70,84% in 120 minutes. The catalyst weight seems to be the most dominant factor for MB degradation.
