Progress in Photocatalytic and Photoelectrochemical Water Splitting of TiO2 Thin Films

二氧化钛薄膜被广泛应用于光催化和光电化学分解水产氢。不同的方法制备的二氧化钛薄膜在形貌、结构等各方面存在差异，光催化和光电化学性能也有所不同。本文总结了近年来纯TiO2薄膜及复合薄膜的制备方法及产氢性能，包括水热法、阳极氧化法、磁控溅射法、模板法、原子层沉积法等，并比较了其光电流密度和产氢量。 TiO2 thin films are widely used in photocatalytic and photoelectrochemical water splitting for aquatic hydrogen production. Titanium dioxide films prepared by different methods differ in morphology, structure and properties. In this paper, various preparation methods have been summarized, such as hydrothermal method, anodic oxidation method, magnetron sputtering method, template method and atomic layer deposition method, which are used for fabrication of TiO2 thin films. Photocurrent density and hydrogen production of the thin films were compared.
