• Red phosphorus is a promising photocatalyst with wide visible‐light absorption up to 700 nm, but the fast charge recombination limits its photocatalytic hydrogen evolution reaction (HER) activity. Now, [001]‐oriented Hittorf's phosphorus (HP) nanorods were successfully grown on polymeric carbon nitride (PCN) by a chemical vapor deposition strategy. Compared with the bare PCN and HP, the optimized PCN@HP hybrid exhibited a significantly enhanced photocatalytic activity, with HER rates reaching 33.2 and 17.5 μmol h−1 from pure water under simulated solar light and visible light irradiation, respectively. It was theoretically and experimentally indicated that the strong electronic coupling between PCN and [001]‐oriented HP nanorods gave rise to the enhanced visible light absorption and the greatly accelerated photoinduced electron–hole separation and transfer, which benefited the photocatalytic HER performance. [001]‐oriented hexagonal‐shaped Hittorf's phosphorus (HP) nanorods with exposed {110} facets were grown on polymeric carbon nitride (PCN) for boosting photocatalytic hydrogen evolution from pure water. The enhanced visible light absorption and accelerated charge transfer efficiency through the P−N bonds and the [001]‐oriented HP nanorods were crucial for the improved photocatalytic activity.
