Abstract
Fe/N-based biomass porous carbon composite(Fe/N-pCarbon)was prepared by a facile high-temperature carbonization method from biomass,and the effect of Fe/N-pCarbon on the thermal decomposition of energetic molecular perovskite-based material DAP-4 was studied.Biomass porous carbonaceous ma-terials was considered as the micro/nano support layers for in situ deposition of Fe/N precursors.Fe/N-pCarbon was prepared simply by the high-temperature carbonization method.It was found that it showed the inherent catalysis properties for thermal decomposition of DAP-4.The heat release of DAP-4/Fe/N-pCarbon by DSC curves tested had increased slightly,compared from DAP-4/Fe/N-pCarbon-0.The decomposition temperature peak of DAP-4 at the presence of Fe/N-pCarbon had reduced by 79℃ from 384.4℃(pure DAP-4)to 305.4℃(DAP-4/Fe/N-pCarbon-3).The apparent activation energy of DAP-4 thermal decomposition also had decreased by 29.1 J/mol.The possible catalytic decomposition mecha-nism of DAP-4 with Fe/N-pCarbon was proposed.
