Preparation of 3DOM CoFe2O4 nanomaterials and their highly efficient catalysis in the thermal decomposition of AP

Abstract

Developing efficient ammonium perchlorate (AP) thermal decomposition catalytic nanomaterials is necessary and challenging. To achieve this goal, three-dimensional ordered macroporous (3DOM) spinel structure CoFe 2 O 4 (3DOM CoFe 2 O 4 ) were prepared by using a simple impregnation method. The prepared 3DOM COFe 2 O 4 has ordered and interconnected macroporous channels, which provide a large number of catalytic active site. After the addition of 2 wt% 3DOM CoFe 2 O 4 catalyst, the THTD value of AP decomposition was reduced by 101.81 ℃, and the decomposition activation energy was reduced from 178.42 kJ mol -1 to 134.21kJ mol -1 . It can be foreseen that 3DOM CoFe 2 O 4 is a very attractive AP thermal decomposition catalyst, which may open up new perspectives for the application of iron based materials as AP based solid propellant catalysts.
