单质直接合成CuS及其催化分解高氯酸铵

Synthesis of CuS by Direct-Reaction and Their Thermal Degradation of Ammonium Perchlorate

室温下通过单质直接合成法,在氯化胆碱与乙二醇以物质的量比1∶2混合制得的低共熔溶剂中合成了微米级的花状CuS球体。利用XRD、EDS、SEM等表征手段对CuS进行了分析,并对花状CuS微球的形成机理作了深入的讨论。同时,利用差热分析(DTA)技术考察了CuS微球对高氯酸铵(AP)热分解的催化效果。结果表明,花状CuS微球对热分解高氯酸铵具有很好的催化效果。添加质量分数2%CuS的高氯酸铵的开始和结束分解温度分别降低了30℃和132℃。

The flower-like CuS microspheres has been synthesized through elemental-direct-reaction at room temperture in the n（C5H14ONCl）/n（EG）=1∶2based deep eutectic melt.The prepared CuS sample was characterized by XRD,EDS,SEM and so on,and the formation mechanism of flower-like CuS microspheres has been discussed. Meanwhile,the thermal decomposition of ammonium perchlorate（AP）has been investigated by DTA technique.The results show that：the flower-like CuS microspheres has a good catalytic effect on the thermal decomposition of ammonium perchlorate.The starting and ending decomposition temperature of ammonium perchlorate which added 2% CuS were decreased by 30 ℃ and 132 ℃,respectively.
