Abstract
The invention relates to the use of nanocatalysts with a high catalytic activity for the thermal decomposition of ammonium perchlorate (AP). To obtain these materials, magnetite nanoparticles (Fe3O4 NPs) were functionalized with two different groups of amine derivatives, tertiary amine (Fe3O4 NPs-A1) and quaternary amine (Fe3O4 NPs-A2). These nanocatalysts allow a lower activation energy to be obtained, accelerating the thermal decomposition of ammonium perchlorate.
