Graphdiyne: research advances in synthesis strategy

Over the past 15 years, the new carbon allotrope graphdiyne (GDY) has been artificially synthesized and has rapidly garnered attention in fields such as energy, catalysis, electronics, and healthcare. Despite its promising potential, the synthetic methods for GDY and its derivatives have been constrained by limitations in application scenarios. This mini-review provides an overview of the synthetic methods for GDY developed in the past 15 years, including the synthesis of pristine GDY on Cu foil, interface-limited synthesis (liquid-liquid, gas-liquid, and solid-liquid interfaces), explosion techniques, chemical vapor deposition, and the preparation of GDY derivatives. The advancement of these methods has significantly broadened the range of applications for GDY-based nanomaterials across various scientific fields. This review not only summarizes GDY synthesis techniques but also discusses key factors influencing the quality of GDY synthesis, offering a novel perspective for the design of GDY-based nanomaterials.
