Post department of mineral sciences smithsonian institution washington dc 20560 0119 abstract manganese oxide minerals have been used for thousands of years by the ancients for pigments and to. Like many monoxides mno adopts the rock salt structure where cations and anions are both octahedrally coordinated.
Manganese oxides with different crystal structures were prepared by the facile hydrothermal method. Crystal structures and economic and environmental significance jeffrey e. Also like many oxides manganese ii oxide is often nonstoichiometric.
Post department of mineral sciences smithsonian institution washington dc 20560 0119 abstract manganese oxide minerals have been used for thousands of years by the ancients for pigments and to clarify glass and today as ores of mn metal catalysts and battery material. The difference in activity is discussed in terms of surface area structure and oxygen mobility. The crystalline phase effect of the manganese oxides was explored in detail.
Its composition can vary from mno to mno 1 045. α mno 2 with nanorod shape possesses higher catalytic activity. Manganese iv oxide is the inorganic compound with the formula mno 2 this blackish or brown solid occurs naturally as the mineral pyrolusite which is the main ore of manganese and a component of manganese nodules the principal use for mno 2 is for dry cell batteries such as the alkaline battery and the zinc carbon battery.
Mno 2 is also used as a pigment and as a precursor to other manganese.
