In this study， two ferrocene-based catalysts， ［FcCH₂N（CH₃）₃⁺］［PbCl₃^-］·CH₃CN （1） and ［FcCH₂N（CH₃）₃⁺］₅［BF₄^-］₄［I^-］ （2） （where Fc= Ferrocene）， were selected as the research objects to systematically investigate and evaluate their regulatory effects on the combustion performance of solid propellants.TG-DSC tests revealed that both catalysts exhibit excellent thermal stability， with decomposition temperatures of 433.3 ℃ and 481.6 ℃， respectively. The catalytic effect of the two compounds on the thermal decomposition of ammonium perchlorate （AP） was studied via DSC. When the mass fraction of the added catalyst was 3%， compounds 1 and 2 reduced the thermal decomposition temperature of AP by 48.9 ℃ and 61.1 ℃， respectively. To further verify the practical application efficiency of the catalysts， their catalytic performance was evaluated based on a hydroxyl-terminated polybutadiene （HTPB） solid propellant formulation. When compounds 1 and 2 were incorporated into the formulation as combustion catalysts at a mass fraction of 2.5% respectively， the burning rate of the propellant increased from 4.06 mm·s^-1 to 8.99 mm·s^-1 and 9.06 mm·s^-1 under a combustion chamber pressure of 3 MPa. Within the pressure range of 3-10 MPa， the pressure exponent of the propellant decreased from 0.32 to 0.24 and 0.16， respectively.In summary， compound 2 possesses outstanding combustion catalytic performance and holds potential application prospects in high-performance solid propellant systems.
