beta-Graphdiyne (-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 -GDY has not been realized yet, and the measurement of its intrinsic properties remains elusive. In this work, -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 x 10(-6) S m(-1) and the work function of 5.22 eV. TiO2@-GDY nanocomposite is then prepared and presented with an enhancement of photocatalytic ability compared to pure TiO2.
