How to prepare MNO2 through 50 %mn (NO3) 2

Manganese nitrate is decomposed into manganese dioxide (S) and nitric oxide (G) under the condition of 200 degrees Celsius steam conditions.One gram of manganese nitrate can absorb 147.455kj
(theoretical heat absorption is the difference between the product and the standard of the reactor Moore)

Heating and evaporating water, roasting above 450 degrees after drying.

First steam the solution, and then bake at 400 ° C under the atmosphere of the oxygen to get MNO2; at this time, the MNO2 obtained at this time is smaller than the surface area, only about 10.

I used to make a catalyst carrier and penetrate manganese dioxide after impregnating manganese nitrate. Do you mean that manganese dioxide is decomposed by manganese nitrate alone?Why not buy it alone

The solution gel method is used to add some manganese ion complexing agents and organic solvents to the nitrate solution to steam dry solvents under certain conditions to get gel and then roast organic solvents at a certain temperature.

You are more difficult. I do n’t know what the manganese dioxide you need to prepare?You can use manganese to decompose directly, and you can definitely get part of manganese dioxide, but you must be a mixture. If you use it for experiments, it is more troublesome to purify.
