Is there an industrial process that produces hydrogen with potassium oxide as a catalyst?

Or is there a process for the production of potassium oxide that has hydrogen as a by-product?


1 Answer 1


The Wikipedia page of potassium oxide states:

Potassium hydroxide cannot be further dehydrated to the oxide but it can react with molten potassium to produce it, releasing hydrogen as a byproduct.

$$\ce{2KOH + 2K <=> 2K2O + H2 ^}$$

  • $\begingroup$ Would you have a mixed alkali metal oxide if the following takes place: $$\ce{2Na + 2KOH ->[\Delta] 2NaOK + H2}$$ $\endgroup$
