Manganese dioxide also catalyses the decomposition of hydrogen peroxide to oxygen and water: 2 H 2 O 2 → 2 H 2 O + O 2. Manganese dioxide decomposes above about 530 °C to manganese(III) oxide and oxygen. At temperatures close to 1000 °C, the mixed-valence compound Mn 3 O 4 forms. Higher temperatures give MnO, which is reduced only with ...
It is prepared commercially by reduction of MnO 2 with hydrogen, carbon monoxide or methane, e.g.: [2] MnO 2 + H 2 → MnO + H 2 O MnO 2 + CO → MnO + CO 2. Upon heating to 450 °C, manganese(II) nitrate gives a mixture of oxides, MnO 2-x, which can be reduced to the monoxide with hydrogen at ≥750 °C. [6]
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Manganese oxide is any of a variety of manganese oxides and hydroxides. [1] These include Manganese(II) oxide, MnO; Manganese(II,III) oxide, Mn 3 O 4; Manganese(III) oxide, Mn 2 O 3; Manganese dioxide, MnO 2; Manganese(VI) oxide, MnO 3; Manganese(VII) oxide, Mn 2 O 7; Other manganese oxides include Mn 5 O 8, Mn 7 O 12 and Mn 7 O 13.
In enzymology, a manganese peroxidase (EC 1.11.1.13) is an enzyme that catalyzes the chemical reaction 2 Mn(II) + 2 H + + H 2 O 2 ⇌ {\displaystyle \rightleftharpoons } 2 Mn(III) + 2 H 2 O The 3 substrates of this enzyme are Mn(II) , H + , and H 2 O 2 , whereas its two products are Mn(III) and H 2 O .
