What catalysts were explored?

The same with N2O. At least one facility in decomposes it to run a small,
supersonic wind tunnel. With a bit tweaking, it's possible to produce
temperature and air conditions approximating those experienced at
supersonic
speeds with the decomposition being the primary source of heat and pumping
energy. We worked on a similar approach for a test setup with Northrop
Grumman a few years ago. I evaluated a number of catalysts to lower the
continuous exothermic decomposition temperature of N2O at the time and
scared myself silly at one point. As a gas, it has a decomposition
expansion
ratio of well over 1000:1 which is somewhat manageable. When going directly
from liquid to gas, it can be quite sharp and energetic. It's important to
design the system taking that into account.

Sure you can breathe it, after you (a) decompose it completely and (b) cool
the results. The same is true of N2O4, actually.
(In fact, there have been a couple of serious design proposals in which
N2O4, present in quantity as main-propulsion oxidizer, would also be
decomposed to provide nitrogen and oxygen for the cabin air. Gak. This is
why you want to insist that the design engineers fly in the spacecraft, not
as a perk but as a job requirement...)
