AB Cobalt, manganese, and aluminum oxide−based bulk catalysts for decomposition of nitrous oxide (N2O) in space thrusters were prepared by the coprecipitation method. Nitrate solutions of cobalt, manganese, and aluminum were coprecipitated in a K2CO3 solution at 298 K, with pH adjusted to 10 by adding a KOH solution. The product was filtered, washed, dried, extruded, and calcined at 1173 K. The catalyst performances were evaluated in N2O decomposition using a 2 N thruster, and the experimental results were compared to theoretical values. In addition, the performances of the bulk catalysts was compared to those of the conventional catalyst (5% Rh2O3/Al2O3) for N2O decomposition.
