With the increasing concern over the global energy crisis and the greenhouse effect caused by carbon dioxide emission, the development of carbon-neutral and renewable- energy conversion technologies has attracted considerable interest in both the scientific and industrial communities. Graphdiyne (GDY), inserting the diacetylenic linkages (−C≡C−C≡C−) between two bonded carbons in graphene, is a novel allotrope of carbon. The sp- and sp2-hybridized two-dimensional network endows GDY with high degree π-conjunction, uniform pores, natural bandgap and excellent electrical conductivity. These natural structural features render GDY a promising candidate for energy conversion. In this presentation, I will introduce some basic concepts of graphdiyne and complie some stories to illustrate how to take advantage of graphdiye to design the efficient catalytic systems for energy conversion
