Study on the State Change of Ir/Al₂O₃ Catalyst by Decomposition of Ammonium Dinitramide (ADN) Based Low-Toxicity Monopropellant

The change of the Ir/Al₂O₃ catalyst before and after the reaction with ADN based low-toxicity monopropellant was confirmed. The catalyst were recovered after decomposition reaction with propellant in a monopropellant thruster at 350 °C preheating condition. Catalyst analysis was performed using a sc...

Summary:The change of the Ir/Al₂O₃ catalyst before and after the reaction with ADN based low-toxicity monopropellant was confirmed. The catalyst were recovered after decomposition reaction with propellant in a monopropellant thruster at 350 °C preheating condition. Catalyst analysis was performed using a scanning electron microscope (SEM) and Brunauer-Emmett-Teller (BET) analyzer. The change of the catalyst specific devices.
