通过液相合成法,利用油酸作为形貌导向剂,通过控制油酸的用量,制备出不同形貌的Cu_2O催化剂。其中,外露面为{110}的十二面体Cu_2O单晶,对高氯酸铵(AP)的低温分解的催化效果最佳,使AP的低温分解温度降低约61℃,使其分解峰值温度降到269℃。此外,当十二面体Cu_2O单晶的添加量由2%增加到5%时,AP的低温阶段分解的质量分数由25.1%增加至98.1%。
By means of liquid-phase synthesis method, oleic acid was used as the morphology-oriented agent, and Cu2O catalysts with different morphologies were prepared by controlling the amount of oleic acid. Among them, the dodecahedron Cu_2O monocrystal with {110} exposed surface has the best catalytic effect on the low-temperature decomposition of ammonium perchlorate (AP), and lowers the pyrolysis temperature of AP by about 61 ℃ and decomposes its peak temperature To 269 ° C. In addition, when the amount of dodecahedral Cu 2 O single crystals increased from 2% to 5%, the mass fraction of AP decomposition at low temperature increased from 25.1% to 98.1%.
