Development of a novel 2Dseparation membrane:Graphdiyne membrane

石墨炔是由sp杂化的二炔键将sp^(2)杂化的苯环连接而形成的具有二维平面网络结构的新型全碳材料,自发现以来就迅速成为研究热点,在催化、电子、能源和膜分离领域均具有重要的研究价值,尤其是大面积石墨炔膜的合成,推进了石墨炔从理论研究迈向实验研究.与石墨烯不同(不透性),石墨炔具有独特大三角形孔道结构,可为气体分子和水分子的传输提供通道且对金属离子具有吸附和截留作用,因此,石墨炔是理想的二维分离膜材料之一,开展石墨炔作为分离膜的研究工作具有重要的理论和应用价值.本文在介绍石墨炔的合成与制备方法的基础上,评述近年来有关石墨炔作为分离膜方面的研究进展,并对石墨炔分离膜的未来研究发展方向进行展望.

Graphdiyne is a novel all-carbon material with 2 D planer network structure,which is connected benzene rings(sp^(2))through diyne bond(sp).Since its discovery,graphdiyne has rapidly become a hotspot,which has important research value in the fields of catalysis,electronics,energy and membrane separation.In particular,the synthesis of graphdiyne membrane with large area has promoted the graphdiyne membrane from theoretical research to experimental research.Unlike graphene(impermeability),graphdiyne has a unique triangular pore structure,provide the transmission of gas and water molecules.Graphdiyne also has adsorption and interception effect for metal ions.Therefore,graphdiyne is one of the ideal 2 D materials for separation membranes and the study of graphdiyne as separation membrane has important theoretical and application value.Based on the introduction of the synthesis and preparation methods of graphdiyne,the recent research progress of graphdiyne as separation membrane is reviewed in this paper,and the future development direction of graphdiyne separation membrane is prospected.
