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. TiO2 nanotube arrays are intensively investigated as TiO2 catalysts. In comparison to a TiO2 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 TiO2 nanotube arrays and their modification methods, and we highlight recent progress in the generation of H-2 on TiO2 nanotube-array-based materials. Finally, challenges associated with industrial application of this photocatalytic technique are also emphasized.
