Preparation of MnO2 from manganese natural ore
Owing to wide applications of manganese oxides in waste water treatment, fertilizers, catalysis, sensors, super capacitors and rechargeable batteries has got novel attention worldwide. Natural ore of manganese were crushed manually and heated to dissolve in concentrated HCl. This solution was treat...

Owing to wide applications of manganese oxides in waste water treatment, fertilizers, catalysis, sensors, super capacitors and rechargeable batteries has got novel attention worldwide. Natural
ore of manganese were crushed manually and heated to dissolve in concentrated HCl. This solution was treated with potassium ferrocyanide to remove iron and other metallic unwanted particles. The precipitated powder was treated with potassium hydroxide to separate out manganese. Compound formation of MnO2 powder is confirmed using FTIR, XRD. Microstructure is characterized using SEM technique. Band gap is determined using UV-visible spectroscopy. Compound formation, grain size and surface characteristics before and after treatment are discussed in this paper. Further improvement towards the formation of nanoparticles is in progress. |
