Abstract Global research efforts aimed at substituting fossil fuels with clean energy sources have been intensified to tackle the energy crisis and associated environmental challenges. Nevertheless, a thorough transition to clean energy necessitates the discovery of new materials that continuously revolutionize the efficiency of energy conversion. Graphdiyne (GDY), a promising carbon allotrope, has garnered substantial interest across various disciplines. Notably, as an emerging energy conversion material, GDY exhibits unique structure and properties that distinguish it from conventional carbon materials, including a highly conjugated and large π structure network, rich chemical bonds, highly non‐uniform charge distribution, as well as the 2D electronic fast transfer channels and 3D ionic channels. This review offers an overview of the recent advancements of GDY in the field of energy conversion, including hydrogen energy conversion, artificial photosynthesis, solar cells, fast‐charging batteries, and new energy conversion devices based on the reversible alkyne‐to‐alkene conversion of GDY.
