Fabrication of graphdiyne and its analogues for photocatalytic application

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 disciplines. As field, this work, we summarize important synthesis strategies including classical synthesis, vapor deposition, explosion approach, interface-assisted methods. We also elaborate recent modifications to regulate structure properties from viewpoint metal doping, non-metal heterostructure construction. Meanwhile, achievements progress development energy environmental applications photocatalysis are highlighted. Lastly, challenges potential developments catalytic research given at end article.
