Progress in energy-related graphyne-based materials: advanced synthesis, functional mechanisms and applications
Graphynes (GYs) are the new star carbon isomers with two-dimensional layered in-plane porous structures, which are composed of sp- and sp2-hybrid carbon atoms. These special features result in their unique topological and electronic structures, high charge mobility and excellent electronic transport properties. All of these advanced properties of GYs make them promising in various applications. In the GY family, graphdiyne (GDY) was the first successfully prepared member, so it attracted the most attention. In this review, the recent progress on the synthetic strategies, functional mechanisms and applications of GDY and other GYs in the fields of energy storage/conversion are summarized, and the challenges hindering their large-scale fabrication toward practical applications are analyzed. Finally, the possible research directions for overcoming the challenges are proposed based on the development trend and perspectives of GYs. It is hoped that this review is helpful for deeply understanding GYs and GY-based materials.
