石墨炔:一种用于合成水污染物有效吸附剂的新型炭材料

A review of graphdiyne:A new material for synthesizing effective adsorbents for aqueous contaminants

石墨炔(GDY)是一种新生的二维材料,其在去除水溶液中污染物的研究方面引起了广泛关注。GDY是sp和sp2杂化碳原子的框架,其在二维对称网络中存在苯环和二乙基键,因此具有优异的共轭性、独特的可调谐电子性能、以及优异的化学和热稳定性。GDY的分子中有C≡C键,且具有均匀分布的三角形孔,可提供更多的反应位点和多种反应路径。因而,GDY具有吸附性,其作为吸附剂时在去除污染水中的油、有机污染物、染料和金属方面表现优异。在已发表的文献中,GDY被用作吸附剂的报道十分有限。本文综述了GDY的合成方法、GDY作为吸附剂的应用以及GDY基吸附剂的表征,并展望了GDY在污染物修复中的应用前景。

Graphdiyne(GDY),a new two-dimensional(2D)carbon molecule,is expected to have applications in the removal of contaminants from aqueous media.It has superior conjugation,unusual and varied electronic properties,and exceptional chemical and thermal stability because of its framework of sp and sp2 hybridized carbon bonds that are combined to produce benzene rings and diacetylenic bonds in a two-dimensional symmetrical network.Its molecular chemistry is the result of it having carbon-carbon triple bonds,with a regular distribution of triangular pores in its structure,which provide reaction sites and various reaction pathways.GDY is an adsorbent with an excellent efficiency for the removal of oil,organic pollutants,dyes,and metals from contaminated water,but there is limited evidence of it being used as an adsorbent in the literature.This review discusses its synthesis and its use as an adsorbent together with its prospects for pollutant removal.
