The Cover Feature shows the bilayer TiO 2 /α‐Fe 2 O 3 nanorod arrays modified with Cu:NiO x hole transfer layer and Co‐Pi co‐catalyst as a photoanode for efficient solar water splitting. The advantages for the combination of bottom‐up engineering of electron–hole transport channels and OER cocatalyst modification are demonstrated. A remarkably enhanced photocurrent density of 2.43 mA cm −2 at 1.23 V RHE under 1 sun illumination and almost no activity attenuation after long‐time operation are achieved.
