| titleOfInvention | Method for preparing gamma-type graphite single alkyne nano carbon material based on benzene precursor |
| abstract | The invention belongs to the technical field of nano carbon materials, and particularly relates to a method for preparing a gamma graphite single alkyne nano carbon material based on a benzene precursor. The invention replaces the solid-phase hexa-halogenobenzene with the liquid-phase benzene as sp 2 The precursor hybridized with carbon atoms is subjected to mechanochemical action with calcium carbide and subsequent heat treatment process to synthesize the gamma-type graphite monoacyne. Compared with various graphite diyne materials, the method has the advantages of simple synthesis process, short synthesis time and low equipment requirement. The invention replaces expensive hexahalobenzene with cheap benzene, which can greatly reduce the preparation cost; meanwhile, solid-liquid interface reaction with good contact and high raw material conversion rate replaces solid-solid interface reaction with limited contact area and low raw material conversion rate, so that the yield and the productivity can be improved; furthermore, the mechanochemical method and the heat treatment are industrially mature processes, and the commercialization of the gamma-type graphite monoalkyne is easy to realize. The obtained product is a p-type semiconductor, and has application prospect in the fields of electrocatalytic oxygen production catalysts, photocatalytic co-catalysts, hole transport materials and lithium ion battery cathode materials. |
