Photocatalytic hydrogen (H 2 ) generation in a water splitting process has recently attracted tremendous interest because it allows the direct conversion of clean and unlimited solar energy into the ideal energy resource of H 2 . For efficient photocatalytic H 2 generation, the role of the photocatalyst is critical. With increasing demand for more efficient, sustainable, and cost‐effective photocatalysts, various types of semiconductor photocatalysts have been intensively developed. In particular, on the basis of its superior catalytic and tunable electronic properties, nitrogen‐doped graphene is a potential candidate for a high‐performance photocatalyst. Nitrogen‐doped graphene also offers additional advantages originating from its unique two‐dimensional sp 2 ‐hybridized carbon network including a large specific surface area and exceptional charge transport properties. It has been reported that nitrogen‐doped graphene can play diverse but positive functions including photo‐induced charge acceptor/meditator, light absorber from UV to visible light, n‐type semiconductor, and giant molecular photocatalyst. Herein, we summarize the recent progress and general aspects of nitrogen‐doped graphene as a photocatalyst for photocatalytic H 2 generation. In addition, challenges and future perspectives in this field are also discussed.
