Catalytic effect of 2D-layered energetic hybrid crystals on the thermal decomposition of 3-nitro-2,4-dihydro-3H-1,2,4-triazol-5-one (NTO)

This study deals with the evaluation of the catalytic activity of some highly energetic coordination polymers of triaminoguanidine-transition metal (T-M) complexes, with or without graphene oxide (GO)-T, on the thermal decomposition of NTO. Their catalytic activity was investigated by differential scanning calorimetry (DSC). Isoconversional integral kinetic methods, viz., iterative Flynn-Wall-Ozawa, iterative Kissinger-Akahira-Sunose, Sbirrazzuoli methodology and Trache-Abdelaziz-Siwani methods have been applied to the DSC experimental data to determine the different kinetic parameters. The obtained results displayed that all of the used catalysts exhibited higher catalytic activity and the peak temperature of decomposition has greatly decreased. The apparent activation energies of decomposition were reduced by more than 180 kJ/g.
