Synthesis and Applications of Graphdiyne Based Zerovalent Atomic Catalysts

Atomic catalysts（ACs） are new types of catalysts with the characteristics of zerovalent metal atoms anchored on the substrates， and have been the research frontier in the field of catalysis due to their unique and fascinating properties such as higher atomic utilization， higher selectivity， excellent catalytic activity and stability. Graphdiyne（GDY） based zerovalent ACs are stabilized by the unique incomplete charge transfer between metal atoms and GDY， which solves the problem of easy migration and aggregation of traditional singe-atom catalysts. In this review， the synthesis， structures and characterizations of GDY based zerovalent atomic catalysts were first introduced. Next， the latest research advances of GDY based zerovalent atomic catalysts in many fields（e. g.， the ammonia production， hydrogen production， overall water splitting， CO₂ fixation and conversion， etc.） were discussed. This review provides an important research idea for the design and synthesis of new concept high-performance catalytic materials.
