摘　　要：以均苯三甲酸和乙酸锰为原料,应用机械化学法（即高速气流法）低温固相合成了锰金属有机框架（Mn-BTC）材料,并通过XRD、FTIR、TG、SEM对Mn-BTC的结构进行了表征。以Mn-BTC为前体制备了Mn2O3,考察了其对高氯酸铵（AP）热分解的催化作用。结果表明：相比传统液相扩散法合成Mn-BTC需要24 h,高速气流法只需要10 min,并且合成操作简便、耗能低、效率高、绿色环保、易于工业化生产。与液相扩散法相比,以高速气流法合成的Mn-BTC为前体制备的Mn2O3具有更好的AP催化效果,可使其高温分解（HTD）温度降低158℃。A high-speed air flow method was used to synthesize porous manganese-based metal-organic framework （Mn-BTC） at low temperature with manganese acetate and trimesic acid as raw materials.The resultant Mn-BTC was characterized by means of XRD, FTIR, TG and SEM. Subsequently, Mn2O3 was obtained by direct pyrolysis of Mn-BTC. Moreover, the catalytic effect of Mn2O3 on the decomposition of ammouiun perchlorate （AP） was studied in detail. The results showed that the required time for synthesizing Mn-TBC by high-speed air flow method was only 10 min, which was far shorter than that by traditional liquid-phase diffusion synthesis method （24 h）. The synthesis process of high-speed air flow method has many advantages, such as simple operation, low energy consumption, high efficiency, environmental friendliness and easy to industrial production. Compared with Mn2O3 from the precursor prepared by liquid-phase diffusion method, the Mn2O3 prepared by high-speed air flow method exhibited better catalytic effects on the decomposition of AP, and it made the temperature of high temperature decomposition （HTD） of AP reduce by 158℃.
