摘要:
为研究氮掺杂氧化石墨烯对环四亚甲基四硝胺(HMX)热分解性能的影响,采用Hummer法制备出氧化石墨烯(GO),然后以尿素为氮源,通过水热还原法得到一种氮掺杂氧化石墨烯(N-GO);采用X-射线粉末衍射仪(XRD)、扫描电子显微镜(SEM)、X-射线光电子能谱仪(XPS)及傅里叶红外光谱仪(FT-IR)对其结构进行了表征,并将其复合到HMX中得到N-GO/HMX,采用差示扫描量热法研究了氮掺杂氧化石墨烯对HMX的催化热分解作用。结果表明,氮掺杂氧化石墨烯对HMX的热分解催化活性比未掺杂的石墨烯好,可使HMX的放热分解温度从283.16℃提前至281.96℃,表观活化能从514.61 kJ/mol降至484.36 kJ/mol,指前因子从1046.86 s-1降至1044.05 s-1。这是源于N原子掺杂进入石墨烯骨架后,引入未配对的电子对,从而增加了石墨烯表面电荷密度和可参与反应的活性位点,进而促进HMX的分解。
Abstract:
In order to study the effects of N-doped graphene oxide (N-GO) on the thermal decomposition of cyclic tetramethylene tetranitramine (HMX), it was obtained by hydrothermal reduction using graphene oxide (GO), which was prepared by the Hummer method, and urea as the nitrogen source. The as-prepared N-GO was characterized by X-ray diffraction apparatus (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR). Then the N-GO/HMX composite was achieved by combining HMX and N-GO. The catalytic effects of N-GO on the thermal decomposition of HMX were evaluated by differential scanning calorimetry (DSC). The results show that N-GO is more effective in promoting the thermal decomposition of HMX than rGO. In the existence of N-GO, the exothermic decomposition temperature of HMX is decreased from 283.16℃ to 281.96℃. Moreover, the corresponding apparent activation energy and pre-exponential factor are decreased from 514.61 kJ/mol and 1046.86 s-1 to 484.36 kJ/mol and 1044.05 s-1, respectively. The promoted decomposition of HMX is attributed to the increased charge densities and catalytic active sites on the surface of GO, which is due to the lone electron pairs introduced to GO after N-atom doping.
