Abstract
Manganese oxide is an important compound in nature for the transformation of various
compounds into simpler compounds. Synthesis of manganese oxide can be carried out
using the sol-gel method. The aim of this research is to examine the effect of calcination
temperature on the characteristics and catalytic activity of MnOx/ACKS composites.
The synthesis of the MnOx/ACKS composite was carried out by mixing KMnO4,
glucose and activated ACKS. The MnOx/ACKS composite was characterized using XRay
Diffraction (XRD). The XRD characterization results show that the MnOx/ACKS
composite consists of a quartz phase and a mixed phase of manganese oxide such as
managanosite, cryptomelane, hausmanite and binnerssite. Degradation of methylene
blue at a concentration of 12.5 ppm, a volume of 5 mL of H2O2 and a composite mass of
25 mg was able to degrade methylene blue by 86.67% within 120 minutes.
