H 2 production from water splitting by a photocatalytic process is one route that can be used to solve global issues related to energy depletion and environmental pollution, and it has attracted a great amount of attention in both the academic and industrial fields. TiO 2 nanotube arrays are intensively investigated as TiO 2 catalysts. In comparison to a TiO 2 powder catalyst, the nanotube arrays have specific advantages, including a large surface area, easy retrievability, uniformly ordered structure, and size‐dependent properties, all of which make them attractive in wide applications including H 2 generation. In recent years, a large amount of work has been done and great progress has been achieved in this field. In this review, we summarize synthetic strategies to prepare TiO 2 nanotube arrays and their modification methods, and we highlight recent progress in the generation of H 2 on TiO 2 nanotube‐array‐based materials. Finally, challenges associated with industrial application of this photocatalytic technique are also emphasized.
