Advances of graphdiyne-supported metal catalysts in thermocatalytic reactions

Supported metal catalysts are widely used in the modern chemical industry. The electronic interaction between supports and active components is of great significance for heterogeneous catalysis. Graphdiyne (GDY), a new type of carbon allotrope with sp-hybridized carbon atoms, π conjugate structure, and electron transmission capability, is a promising candidate as catalyst support. Recent years have witnessed the rapid progress of GDY-supported metal catalysts for different catalysis reactions. Considering that most processes in the current chemical industry are thermocatalytic reactions, we herein give an overview about the advances and particular characteristics of GDY-supported catalysts in these reactions. The geometric structure and electronic properties of GDY are first introduced. Then, the synthesis methods for GDY-supported metal catalysts and their applications in thermocatalytic reactions are discussed, in which the effect of electronic interaction on catalytic performance is highlighted. Finally, the current challenges and future directions of GDY-supported metal catalysts for thermocatalysis are proposed. It is expected that this review will enrich our understanding of the advances of GDY as a superior support for metal catalysts in thermocatalytic reactions.
