Functional Graphdiyne for Emerging Applications: Recent Advances and Future Challenges

Advanced Functional Materials, Год журнала: 2023, Номер 34(4)

Опубликована: Окт. 20, 2023

Abstract Graphdiyne (GDY) is regarded as an exceptional candidate to meet the growing demand in many fields due its rich chemical bonds, highly π‐conjugated structure, uniformly distributed pores, large surface area, and high inhomogeneity of charge distribution. The extensive research efforts bring about a rapid expansion GDY with variety functionalities, which significantly enhance performance including photocatalysis, energy, biomedicine, etc. In this review, synthetic strategies (in situ ex approaches) that are designed rationally functionalize GDY, optimizing their nanostructures by surface/interface engineering dopants or functional groups (heteroatoms/small molecules/macromolecules), building up hierarchical GDY‐based heterostructures highlighted. Theoretical calculations on structural evolution electronic characteristics after functionalization briefly discussed. With elaborate rational structure engineering, applied emerging applications (e.g., hydrogen reaction, CO 2 reduction nitrogen energy storage conversion, nanophotonics, sensors, biomedical applications, etc.) comprehensively Finally, challenges prospects concerning future development nanoarchitectures also presented.
