In nano-thermites, due to improper contacts between the reactants in solid-state reaction, the complete energy release during redox-reaction is still challenging. Here, Fe₂O₃/Al nano-thermite is synthesized with different weight fraction of multi-layered graphene (MLG) nanoplatelets by physical mixing technique. X-ray diffraction reveals that the synthesis method does not change the phase of reactants. The morphology of nano-thermite is examined by scanning electron microscopy and transmission electron microscopy which reveals that MLG nanoplatelets are homogeneously dispersed in the samples. Structural stability of MLG nanoplatelets present in nano-thermite is observed by Raman spectroscopy. The nano-thermite reaction is analyzed by differential scanning calorimetry. The results show that an increase in MLG content in nano-thermite sample Al/Fe₂O₃, from 0 wt% to 12 wt% is responsible for increase in the corresponding exothermic enthalpy from 71 J/g to 1537 J/g. On the contrary, ignition temperature and activation energy of these samples get reduced with increasing MLG.

在纳米级半导体中，由于固态反应中反应物之间的接触不当，在氧化还原反应过程中完全释放能量仍然具有挑战性。在这里，Fe ₂ O ₃通过物理混合技术合成了不同重量分数的多层石墨烯（MLG）纳米片状的/ Al纳米铝热剂。X射线衍射表明该合成方法不会改变反应物的相。通过扫描电子显微镜和透射电子显微镜检查了纳米铁矿的形态，揭示了MLG纳米片均匀地分散在样品中。通过拉曼光谱观察了存在于纳米热液中的MLG纳米片的结构稳定性。通过差示扫描量热法分析纳米铝热反应。结果表明，纳米铝热样品Al / Fe ₂ O ₃中MLG含量增加，从0wt％到12wt％，负责使相应的放热焓从71J / g增加到1537J / g。相反，这些样品的着火温度和活化能随MLG的增加而降低。
