β-Graphdiyne (β-GDY) is a member of 2D graphyne family with zero band gap, and is a promising material with potential applications in energy storage, organic electronics, etc. However, the synthesis of β-GDY has not been realized yet, and the measurement of its intrinsic properties remains elusive. In this work, β-GDY-containing thin film is successfully synthesized on copper foil using modified Glaser-Hay coupling reaction with tetraethynylethene as precursor. The as-grown carbon film has a smooth surface and is continuous and uniform. Electrical measurements reveal the conductivity of 3.47 × 10 S m and the work function of 5.22 eV. TiO @β-GDY nanocomposite is then prepared and presented with an enhancement of photocatalytic ability compared to pure TiO .
β-石墨炔（β-GDY）是二维石墨炔家族的一员，具有零带隙，是一种很有前途的材料，有望在储能、有机电子等领域得到应用。然而，β-GDY 的合成尚未实现，其本征性质的测量也难以捉摸。在这项工作中，我们使用四乙炔基乙烯作为前驱体，通过改进的 Glaser-Hay 偶联反应，成功地在铜箔上合成了含有β-GDY 的薄膜。所生长的碳膜表面光滑，连续且均匀。电测量显示其电导率为 3.47×10 S m，功函数为 5.22 eV。然后制备了 TiO@β-GDY 纳米复合材料，并表现出比纯 TiO 更高的光催化能力。
