The effective thermal decomposition of ammonium perchlorate (AP) is an essential area of research in improving propellant combustion behavior. In this article, non-heavy metal cations such as Co(II), Mn(II), and Cu(II) were used for the preparation of a metal-organic framework based on 5,5′-tetrazole-amine (BTA). The low sensitivity of these compounds is of great importance in energy applications. XRD and FT-IR analyses were used to confirm the MOF structure. Adding MOF alters thermal decomposition processes, according to a thermal analysis obtained from the polymer DSC curve. The strong catalytic activity of the H-MOF for AP thermal decomposition is probably due to the synergistic effect of metal nodes and energetic ligands. The total heat released in the thermal decomposition of AP increased from 535.9 to 2435 J·g −1 , and the high-temperature decomposition peak was dramatically reduced by 67 °C. Finally, we performed kinetic and thermodynamic studies on the thermal decomposition of AP and calculated the activation energy of AP decreased from 91.9 to 72.1 kJ·mol −1  and other parameters.
