We here identify by ab initio calculations a new type of three-dimensional (3D) carbon allotropes that consist of phenyl rings connected by linear acetylenic chains in sp+sp(2) bonding networks. These structures are constructed by inserting acetylenic or diacetylenic bonds into an all sp(2)-hybridized rhombohedral polybenzene lattice, and the resulting 3D phenylacetylene and phenyldiacetylene n...

Graphdiyne (GDY), an emerging two-dimensional all-carbon allotrope, features the coexistence of sp and sp2 hybridized planar carbon atoms. GDY GDY-based materials exhibit unique physical chemical properties, such as well-defined molecular skeleton, ?-conjugated structure, high specific surface area with porosity, good electrical conductivity, which have aroused widespread interest in various di...

Quantum Dots In article number 2101138, Yurui Xue, Feng He, Yuliang Li and co-workers demonstrate controllable growth of iridium oxide quantum dots by exploiting the unique properties graphdiyne. This provides an ideal system to control preparation small size, dot catalysts, fully demonstrating size effects these catalysts in catalytic process, obtaining highly active robust with excellent acid...

A deprotection-free method was developed for the synthesis of graphdiyne (GDY) powder with in-situ formed CuO nanoparticles, as reported by Mohamed Nawfal Ghazzal, Li-Zhu Wu et al. in their Research Article (e202210242). The prepared CuO/GDY demonstrated to be an excellent co-catalyst photocatalytic hydrogen evolution, comparable state-of-art Pt cocatalyst. work will widen use GDY and facilitat...
