Architecture and properties of a novel two-dimensional carbon material-graphtetrayne

Density functional theory study on electrical properties of graphyne propane under tension and compression deformation

“…The results of this study confirmed that the graphyne formed by the sp and sp 2 hybridization state could be prepared by artificial synthesis, which opened up the road for experimental testing of synthesis [7]. Subsequently, experimental reports on the synthesis of graphyne and graphyne-4 in the experiment, which fully demonstrated the excellent editability and diverse geometry of graphyne [5,[8][9][10]. At the same time, the research about the application of charge mobility of graphyne [11,12], mechanical properties [13,14], nanobelt characteristics [15][16][17], and electrodes in lithium batteries [18,19], hydrogen storage and lithium storage [20][21][22][23][24][25][26], and gas separation [27] are also about emerge.…”

Research on the Preparation of Graphdiyne and Its Derivatives

“…[86] Li,L iu and co-workerss ynthesized GTY on the surfaceo fc opper foil by cross-coupling reaction using diiodobutadienea s precursors (Figure 9a-b). [87] Experimental results showedt hat GTY has good thermal stability,l arge pore size and high electron density,w hich are attributed to the high content of sp carbon atoms. Moreover,G TY exhibits excellent rate performance and cycle performance when appliedt ol ithium ion batteries.…”

“…The liquid-phasem ethodi sa lso suitable for the preparation of GDY analogues, Zhang, Liu and co-workers prepared a b-GDY film on the surfaceo facopperf oil by a Glaser-Hayc oupling reaction (Figure 9c-d). [87] Moreover,an ew GDY analogue named 1,3-diyne-linked conjugated micro porousp olymer nanosheets (CMPNs) is composed of two acetylene bonds between four benzene ring groups and abenzene ring group. CMPNs were synthesized by Glaser coupling of 1,3,5-tris-(4-ethynyl-phenyl)-benzene(TEPB)byu sing copper (I) salts as catalysts at room temperature.…”

“…Nowadays, av arietyo fg raphdiyne analogs (such as b-GDY,B en-GDY,atriphenylene-cored analogue, thiophdiyne, graphtetrayne) have been prepared using the designed precursors (tetraethynylethene, 1,3,5-triethinyl-2,4,6-triphenyl-benzol, hexaethynyltriphenylene, tetraethynylthiophene, Exaethynylbenzene and diiodobutadiyne, respectively), which have been prepared by as imple cross-coupling solution reaction.

Carbon-based derivatives from metal-organic frameworks as cathode hosts for Li–S batteries

“…Porous carbon materials with a variety of morphologies from one to three dimensions have been used to immobilize sulfur [42,[95][96][97][98] . Thereinto, two-dimensional porous carbon nanomaterials are quite promising because of ultra-large specific surface area, good electroconductivity and rapid charge transfer [99][100][101] . Recently, Jiang et al proposed a self-template and organic solvent-free approach to synthesize nanosheets of monoclinic ZIF-8 at room temperature, from which 2D hierarchical porous carbon nanosheets (i.e.…”
