英文摘要The hydrothermal treatment of gamma-AlOOH agglomerates was introduced to synthesize nanostructured gamma-AlOOH. Various characterizations were carried out to understand the synthesis procedure and the relationship between the shape of gamma-AlOOH and its accelerating behavior for the thermal decomposition of ammonium perchlorate (AP). XRD, SEM and HRTEM showed that the gamma-AlOOH nanoplates, nanorods and nanocubes with exposed (031), (110) and (001) facets, respectively, could be synthesized under controllable conditions. The DSC results showed that the addition of gamma-AlOOH nanoplates, nanorods and nanocubes to AP remarkably decreased the decomposition temperature of AP from approximately 450 degrees C to 334 degrees C, 345 degrees C, and 357 degrees C, respectively. As the preferred additive, the gamma-AlOOH nanoplate addition resulted in a decrease in the activation energy of AP from 346.29 kJ mol(-1) to 144.73 kJ mol(-1), determined by nonisothermal kinetic analysis. XRD, FT-IR and XPS results revealed that the gamma-AlOOH phase transformed to gamma-Al2O3 and alpha-AlOOH after being used as an additive for the AP decomposition; the excessive surface hydroxyls obtained by the exposed (031) facet of gamma-AlOOH nanoplates, proved to be beneficial for accelerating AP decomposition.
