The catalytic activity of energetic coordination polymers of triaminoguanidine-transition iron, containing gra-phene oxide (GO-T-Fe-T) or not (T-Fe), on the thermolysis of an energetic co-crystal of hydrazinium 3-nitro-1,2,4-triazol-5-one and ammonium nitrate (HNTO/AN) has been investigated. DSC apparatus has been employed to investigate the thermal behavior of the different products. Four isoconversional integral kinetic approaches have been used to calculate the kinetics triplets. The achieved results showed that both of T-Fe and GO-T-Fe-T possess good catalytic activity. The decomposition temperature and the activation energy of the co -crystal were reduced by 31 kJ/mol and by 55 kJ/mol when T-Fe and GO-T-Fe-T are introduced, respectively. Furthermore, using iron as a metal in the catalysts increased the decomposition heat released from the co-crystal. This can be due to the better dispersion of Fe on the GO sheets, which enhanced the decomposition reaction.
