General

What is Manganese (IV) Oxide? Also known as manganese dioxide (MnO2), it is an inorganic compound with a black or dark brown appearance. It's a naturally occurring mineral called pyrolusite and is widely used as a reagent, pigment, and catalyst. A key application is its role as a depolariser in dry-cell batteries.

Frequent Uses

Batteries
This is its most significant industrial use, where it acts as a depolariser in the cathode of dry-cell batteries to prevent the buildup of hydrogen gas and generate electricity.

Pigments
Used as a black or brown inorganic pigment in the manufacture of ceramics and glass. It can also be used to decolourise glass that has been turned green by iron impurities.

Oxidising Agent
In organic synthesis, manganese(IV) oxide is a common reagent used to oxidise organic compounds, such as allylic alcohols.

Catalysis
Acts as a catalyst for various reactions, most notably for speeding up the decomposition of hydrogen peroxide.

Environmental
Nanoparticles of manganese dioxide are used in environmental applications for chemical oxidation and surface catalysis.
