Abstract Incorporating the charge transfer medium between semiconductor and cocatalyst accelerates separation of photogenerated charges, enhancing photoelectrochemical water oxidation performance. However, structure regulation in situ generated by is usually neglected, which would alter injection efficiency holes. Besides, more relevant technologies are necessary to investigate intrinsic action each part on oxidation. Herein, a novel triadic photoanode designed rationally, involving Ti‐doped hematite (Ti‐Fe 2 O 3 ) core, nitrogen‐doped carbon (CN) interlayer, Ce‐doped NiFe‐LDH (NFC) shell. The results like single‐molecule fluorescence short‐pulse transient photocurrent experiments reveal CN not only employs as hole layer facilitate bulk suppress back recombination, but also polishes up OH − absorption conjunction with NFC. Furthermore, exhibits an additional functionality inducing oxygen vacancies Ce 4+ NFC further raise efficiency, expediting generation from absorbed . Consequently, NFC/CN/Ti‐Fe presents significantly higher density than NFC/Ti‐Fe , accomplishing 2.87 mA cm −2 at 1.23 V versus RHE. design multiple‐functional strategic approach for regulating reactant transfer, thereby
