Can manganese dioxide do any catalyst for chemical reactions?
The catalyst is selective
The catalyst is involved in the reaction during the reaction and is reduced to the original composition after the reaction is completed. For example: heating decomposition of potassium permanganate when adding potassium permanganate. Potassium permanganate decomposition process, potassium permanganate is involved in the reaction, the specific way is not clear. And finally appeared with potassium permanganate. Reaction before and after the catalyst morphology changes, particles become powder, powder particles and so on.
the catalyst does not participate in the reaction, such as platinum - rhodium alloy network, nitrogen and hydrogen reaction to produce ammonia. Platinum-rhodium alloy network in the process of providing electrons (or similar effects, the specific is not clear, but does not react itself), before and after the reaction of platinum - rhodium alloy mesh shape has not changed.
