Abstract

The α-FeOOH nanorods were prepared via hydrothermal reaction of Fe(NO3)3·9H2O and KOH at
100℃ for 6h. Then the α-FeOOH nanords were heat treated at different temperautres, and single crystalline and multiporous α-Fe2O3 nanorods were obtained. The phase and morphology of the samples were characterized by XRD and TEM. The heat treatment process was investigated by TGA and FT-IR. The results show that the phase transition of α-FeOOH→α-Fe2O3 occurrs between 239℃ and 259.1℃. The α-Fe2O3 still keeps in rod shape and lots of holes appear on the surface which disappear with the temperature increasing. The catalytic performance of α-Fe2O3 nanorods was studied by decomposition of ammonium perchlorate(AP) based on DTA. The higher-temperature of exothermic peak of AP shifts towards low temperature when α-Fe2O3 nanorods are introduced into the reaction, and the largest decrement reaches 71.4℃ for the α-Fe2O3 nanorods heat treated at 350℃.

Key words： heat treatment; phase transition; ammonium perchlorate; catalytic performance
