Graphene inducing graphitization
WebGraphitization of polymers is an effective way to synthesize nanocrystalline graphene on different substrates with tunable shape, thickness and properties. The catalyst free synthesis results in crystallite sizes on the order of a few nanometers, significantly smaller than commonly prepared polycrystalline graphene. WebOct 15, 2024 · The graphitic carbon nitride (g-C 3 N 4) as a promising high-nitrogen carbon material has attracted abundant attentions in energy storage field. In this work, the N-doped carbon nanotubes (N-CNTs) are synthesized through a facile one-step pyrolysis of g-C 3 N 4 precursor assisting by Ni catalyst.

WebGraphitization, the high temperature conversion of carbon materials into graphite, has been applied to porous and templated carbon materials for decades and represents a facile method of converting biomass or polymer structures into porous graphitic carbon.15–17Such methods have been applied to form hard carbon anodes for sodium and lithium ion … Webgraphitization process. For example, a higher pressure will lower the need for high temperature and vice versa [9]. Studies in recent years have however shown that with the implementation of a catalyst, the needed temperature for the graphitization can be lowered to 800-1300℃ while also increasing the degree of graphitization for the process.
