In this paper, the graphene oxide (GO) doped transition metal (Cu, Co, and Ni) complexes of triaminoguanidine (TAG) have been prepared where the GO serves as the stabilizing agent. The catalytic reactivity of GO stabilized TAG-M (M = Cu, Co, Ni) energetic composites on thermolysis of 1,3,5-trinitro-1,3,5-triazinane (RDX) has been investigated by using DSC/TGA techniques. It has been found that these materials have strong catalytic effects on decomposition of RDX by decreasing the apparent activation energy. Meantime, GO would not only stabilize TAG-M energetic composites but also enhance the thermal stability of RDX due to its high thermal conductivity. The physical models that govern the decomposition processes were also studied, and it has been shown that different reaction processes are accomplished by varying transition metals or in cooperation with GO. The complex catalyst, with improved thermal stability, represents a unique class of catalyst of considerable value for catalytic combustion and safety issue of solid propellants.

三氨基胍的氧化石墨烯稳定的过渡金属配合物对RDX的催化活性

在本文中，制备了三胺胍（TAG）的氧化石墨烯（GO）掺杂的过渡金属（Cu，Co和Ni）配合物，其中GO用作稳定剂。通过DSC / TGA技术研究了GO稳定的TAG-M（M = Cu，Co，Ni）高能复合材料对1,3,5-三硝基-1,3,5-三嗪烷（RDX）热解的催化反应性。。已经发现这些材料通过降低表观活化能对RDX的分解具有强烈的催化作用。同时，GO不仅可以稳定TAG-M高能复合材料，而且由于其高导热性还可以增强RDX的热稳定性。还研究了控制分解过程的物理模型，并且已经表明，通过改变过渡金属或与GO协同完成不同的反应过程。具有改善的热稳定性的复合催化剂代表了独特的一类催化剂，对于催化燃烧和固体推进剂的安全性问题具有相当大的价值。
