A uniform array of Aurivillius phase perovskite PbBi 2 Nb 2 O 9 photocatalyst in a nanorod configuration is fabricated on a conducting glass as a photoelectrode for a photo‐electrochemical water oxidation. Dramatically improved photoactivity is demonstrated for the nanorod electrode compared to a PbBi 2 Nb 2 O 9 particulate electrode. Directional electron transport in crystalline nanorods is faster than percolation through a random polycrystalline particle network.
