Ir with Co/Cu compounds lit off at <200 C. Shell Pt/ Pd/Rh <400 C but less
repeatable and sensitive to loading. GASL and Qualis had some success with
Ir/Pt. There are a number of programs that were published on the subject if
you look them up. The research is expensive in terms of the materials as
well as damaged reactor equipment. In GASL's case, at least one complete
test stand at Huntsville. Catalyst durability and stability are at least two
of the issues that needed to be resolved in most of the investigations. I'm
not aware of anyone coming up with a "silver bullet" that made the approach
practical for propulsion flight hardware where most of the efforts were
focused. NO2/Propane (NOP)
thrusters. An elegant and storable idea but.

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.
