Carbon has three hybridization forms of sp⁻, sp²⁻ and sp³⁻, and the combination of different forms can obtain different kinds of carbon allotropes, such as diamond, carbon nanotubes, fullerene, graphynes (GYs) and graphdiyne (GDY). Among them, the GDY molecule is a single-layer two-dimensional (2D) planar structure material with highly π-conjugation formed by sp⁻ and sp²⁻ hybridization. GDY has a carbon atom ring composed of benzene ring and acetylene, which makes GDY have a uniformly distributed pore structure. In addition, GDY planar material have some slight wrinkles, which makes GDY have better self-stability than other 2D planar materials. The excellent properties of GDY make it attract the attention of researchers. Therefore, GDY is widely used in chemical catalysis, electronics, communications, clean energy and composite materials. This paper summarizes the recent progress of GDY research, including structure, preparation, properties and application of GDY in the field of catalysts.

碳具有SP三个杂交形式^-，SP ^2-和SP ^3-，以及不同形式的组合可以得到不同种类的碳同素异形的，诸如金刚石，碳纳米管，富勒烯，graphynes（GYS）和graphdiyne（GDY）。其中，GDY分子是单层的二维（2D）平面结构具有高度材料π -conjugation由藻组成^-和SP ^2-杂交。GDY具有由苯环和乙炔组成的碳原子环，这使得GDY具有均匀分布的孔结构。此外，GDY平面材料具有一些细微的皱纹，这使GDY的自稳定性优于其他2D平面材料。GDY的优异性能使其吸引了研究人员的注意。因此，GDY广泛用于化学催化，电子，通讯，清洁能源和复合材料。本文综述了GDY的最新研究进展，包括GDY的结构，制备，性质及其在催化剂领域的应用。
