Abstract
In the current chapter, the synthesis of nanosized catalytic particles posed a significant challenge, aimed at facilitating the thermal decomposition of various green propellants, such as hydroxylammonium nitrate (HAN) and ammonium dinitramide nitrate (ADN), with the intention of replacing conventional hydrazine as a monopropellant for satellite reaction control systems (RCS). This chapter delves into the methods employed for preparing catalytic nanoparticles and their impact on the thermal decomposition and combustion characteristics of these propellants. Additionally, the utilization of the developed systems combining {propellants + catalysts} in actual missions and within the industrial sector will be presented, thoroughly examined, and guided.
