Abstract

Fantastic characteristics originate from the unique chemical and electronic structure endow GDY with a bright future for applications in electrochemical energy storage.

Abstract

Graphdiyne as a new allotrope of carbon material was constructed by benzene rings and butadiyne. The large 2D conjugated structure endows graphdiyne with excellent conductivity and flexibility. More importantly, the atomic arrangement of graphdiyne with a unique porous framework structure is very different from the compact structure of other carbon materials, such as graphene and carbon nanotubes. This is of great benefit to the diffusion and transfer of ions and gases. In the meantime, the high specific surface area originating from the pore structure can also provide abundant active sites for the storage of electrons or ions. The high charge density around the acetylenic bond in graphdiyne supplies the adsorption capacity of ions and gases as well as the catalytic ability to some degree. In addition, the mild synthetic route endows graphdiyne with function tunability and good film-forming ability. Benefiting from all these extraordinary properties, graphdiyne would have a bright future for applications in electrochemical energy storage.

Architecture of graphdiyne nanoscale films

Guoxing Li, Yuliang Li, Huibiao Liu … (2010)

We have demonstrated a methodology to generate large area graphdiyne films with 3.61 cm(2) on the surface of copper via a cross-coupling reaction using hexaethynylbenzene. The device based on graphdiyne films for measurement of electrical property is fabricated and shows conductivity of 2.516 x 10(-4) S m(-1) indicating a semiconductor property.

Graphdiyne and graphyne: from theoretical predictions to practical construction.

Yongjun Li, Liang Xu, Huibiao Liu … (2014)

Flat carbon (sp(2) and sp) networks endow the graphdiyne and graphyne families with high degrees of π-conjunction, uniformly distributed pores, and tunable electronic properties; therefore, these materials are attracting much attention from structural, theoretical, and synthetic scientists wishing to take advantage of their promising electronic, optical, and mechanical properties. In this Review, we summarize a state-of-the-art research into graphdiynes and graphynes, with a focus on the latest theoretical and experimental results. In addition to the many theoretical predictions of the potential properties of graphdiynes and graphynes, we also discuss experimental attempts to synthesize and apply graphdiynes in the areas of electronics, photovoltaics, and catalysis.
