Abstract
Copper acetylide is a well-known explosive compound. However, when the size of it crystals is reduced to the nanoscale, its explosive nature is lost, owing to a much lower thermal conductance that inhibits explosive chain reactions. This less explosive character can be exploited for the production of new carbon materials. Generally, amorphous carbon is prepared by carbonization of organic compounds exposed to high temperature, which can induce partial crystallization in graphite. In this work, we present a new method in which the carbonization reaction can proceed at a lower annealing temperature (under 150°C) owing to the highly reactive nature of copper acetylide, thus avoiding crystallization processes and enabling the production of genuinely amorphous carbon materials.
Highlights
Amorphous carbon has been known for a long time under various denominations such as coal, soot, and carbidederived carbon
Amorphous carbon is usually associated with graphite-based materials [1]. It is generally prepared by carbonization of organic compounds exposed to a high temperature, which can induce partial crystallization in graphite [6]
Even though the measurements were taken with the same sample amounts and for the same duration, the peak intensity of the activated carbon was two orders of magnitude lower than that of graphite. This difference is due to the lower crystal quality of the carbon sample: in other words, the amorphousness of the activated carbon resulted in a lower intensity of the X-ray diffraction (XRD) signal
Summary
Amorphous carbon has been known for a long time under various denominations such as coal, soot, and carbidederived carbon. This form of carbon consists of free, reactive carbon, without any crystalline structure. Most carbon materials can be categorized into diamond-likecarbon, graphite-based carbon, and carbyne, which represent the main crystalline forms of carbon, involving sp, sp2, and sp carbon hybridization, respectively [1,2,3,4,5]. Amorphous carbon is usually associated with graphite-based materials [1]. It is generally prepared by carbonization of organic compounds exposed to a high temperature, which can induce partial crystallization in graphite [6]. The activated carbon can no longer be considered as amorphous
