| Summary: | 碩士 === 高苑科技大學 === 化工與生化工程研究所 === 99 === Nano-metallic composites including carbon-metal structured and bimetallic nanomaterials have been synthesized by a self-heating detonation process using high temperatures and high shock waves. This research presents the use of this special system to study the catalytic detonation process and the effect of reaction conditions on conditions and the catalytic conversion of energetic explosives such as RDX into nano materials.
These products of carbon-metal and bimetallic nanoparticles are characterized by XRD, TGA, EDX and TEM techniques. These results show that catalyzed-blast process is possible for a cheaper process and it is also an alternative compared to these high energy and hardware intensive processes to assemble nano-sized carbon-metal hybrid and the bimetallic alloys. The experimental results show that the bimetal compounds can be converted into metallic nanoparticles due to the fast decomposition with a reduction reaction after the detonation and this can be expected for the growth of different composition of carbon-metal and bimetal nanomaterials. The morphology of carbon nanostructures varied with the reaction conditions such as catalyst type, recipes of reactant composition with the use of different metal source.
In this research, a laboratory self-heating detonation process has been successfully designed and a more effective synthesis of carbon nano-materials using this specially system to study the relationship between the experimental conditions and roles of the catalyst types. This approach involving bottom-up nanotechnology is universal and low-cost, and especially it has the potential ability to convert waste energetic explosives to from highly valuable materials, as well as providing the suitable alternatives to reuse the energetic explosive.
