Zeolitic imidazolate framework‐8 (ZIF‐8)‐derived N‐doped graphene analogous polyhedrons (ZNGs) obtained via the direct carbonation of ZIF‐8 are applied to photocatalytic hydrogen evolution for the first time. The contents of different types of nitrogen atoms in ZNGs can be fine‐tuned via the calcination temperature, which significantly influences the hydrogen evolution rate of the ZNGs.
