                         contents of 30% were prepared using the methods of incipient 
                         wetness and incipient coimpregnation wetness and were tested in a 
                         2N microthruster. Their performances were then compared with that 
                         of the Shell 405 commercial catalyst (30% Ir/Al2O3). Tests were 
                         performed in continuous and pulsed regimes, where there are steep 
                         temperature and pressure gradients, from ambient values up to 650 
                         degreesC and 14 bar. Performance stability, thrust produced, 
                         temperature and stagnation pressure in the chamber and losses of 
                         mass were analyzed and compared to the corresponding parameters in 
                         Shell 405 tests. It was observed that the performance of all the 
                         above-mentioned catalysts was comparable to that of the commercial 
                         one, except for in loss of mass, where the values was higher, 
                         which was attributed to the lower mechanical resistance of the
