Graphdiyne: research advances in synthesis strategy

In the past 15 years, the new carbon allotrope graphdiyne (GDY) has been artificially synthesized and has rapidly received close attention in fields such as energy, catalysis, electronic devices, and healthcare etc. The synthetic methods of GDY and GDY derivatives are gradually being improved due to the limitations of application scenarios. This mini-review summarizes the synthetic methods of GDY in the past 15 years, including pristine GDY synthesis on Cu foil, interface limited synthesis (liquid-liquid, gas-liquid, and solid-liquid interface), explosion, chemical vapor deposition (CVD) and the preparation of GDY derivatives etc. The development of these synthetic methods greatly expands the applied range of GDY-based nanomaterials in various scientific frontiers. This review not only summarizes the synthesis techniques of GDY, but also discusses factors such as the quality of GDY synthesis, providing a novel perspective for the design of GDY-based nanomaterials.
