Studies of Homogeneous and Heterogeneous Hydrazine Decomposition for Monopropellant Propulsion Systems.

摘要

The properties of alumina-supported Ir-Ni alloy catalysts for the decomposition of hydrazine have been examined over a range of mixed-metal compositions. The results demonstrate that the addition of Ni to Ir increases the specific catalytic activity, with a maximum at 35 atomic percent Ni, and at the same time reduces the decay in activity caused by the accumulation of reaction products over a range of Ni-Ir alloy compositions.
