This work illustrates the comparison of the physical and chemical characterization of two catalytic beds supporting Pt on Al2O3 with and without an intermediate thin film of mixed Cerium-Zirconium oxide, to be used for H2O2 decomposition in rocket propulsion applications. The characterizations have been carried out by XRD, SEM and EDX analyses before and after conducting propulsive performance tests in a laboratory rocket engine prototype using commercial HTP (High Thrust Peroxide) propellant
