Metal-Based Green Energetic Catalysts for Solid Propellant Combustion Control

Green combustion catalysts have gained significant attention due to their ability to enhance combustion rates while reducing environmental impact. This chapter focuses on the advancements and potential applications of metal oxides, nitrotriazolone (NTO) metal, azoles, and graphene-modified azoles as green combustion catalysts. Metal oxides, such as copper oxide and titanium dioxide, exhibit unique catalytic properties that facilitate rapid fuel oxidation reactions. NTO metal catalysts, which are composite materials consisting of low-sensitivity explosives and metals, have shown remarkable catalytic activity and safety performance. Azole catalysts, characterized by their azole-ring structure, possess favorable combustion catalytic properties. These catalysts exhibit high thermal stability and combustion ability, effectively enhancing combustion rates and efficiency. In conclusion, the investigation of metal oxides, NTO metal, azoles, and graphene-modified azoles as green combustion catalysts offers great potential for advancements in combustion control and environmental sustainability. These catalysts could contribute significantly to the development of more efficient combustion technologies while minimizing environmental impact.
