Earth-Abundant Metal-Based Catalysts for Composite Solid Propellants
Driss Soubane
This chapter offers a comprehensive review of earth-abundant metal-based (EAM) catalysts in solid propellants, tracing the evolution of combustion laws and rocket propulsion principles, including Tsiolkovsky’s logarithmic equation. We explore the historical development and scientific advancements in solid propellant technologies, with a focus on how metals such as iron, manganese, and copper improve burn rates, enhance combustion efficiency, and lower decomposition temperatures. The chapter also examines catalytic mechanisms, addressing the effects of radiation, exothermic catalytic decomposition, and physical transitions, along with the efficiency and durability of EAMs under extreme conditions. Additionally, we assess the impact of metal-organic frameworks on propellant performance and discuss current technologies and future challenges. The chapter concludes by outlining future research directions, including optimizing catalyst compositions, utilizing nanoscale materials, and developing sustainable, high-performance catalysts for long-duration missions.
