本文综述了近年来碳纳米管，特别是单壁碳纳米管在光电化学器件和液体电解质电池电极光活性层中的应用进展。电泳沉积、分层沉积、自组装单层技术和喷涂等多种方法已被用于在半导体或金属电极上形成单壁碳纳米管薄膜。在光电化学器件和电池中，单壁碳纳米管可以作为有效的电荷传输途径抑制反向电子转移，也可以作为一维纳米和介观支架组装光活性分子以促进电荷通过分子阵列的传输。这些结果表明，单壁碳纳米管独特的光学、电学和结构特性有助于开发高效的基于碳纳米管的光电化学器件和电池。
This review article deals with recent advancements on the application of carbon nanotubes, especially single-walled carbon nanotubes (SWNTs), to a photoactive layer on electrodes of photoelectrochemical devices and cells using liquid electrolytes. Versatile methodologies such as electrophoretic deposition, layer-by-layer deposition, self-assembled monolayer technique, and spray-coating have been adopted to form films of SWNTs on semiconducting or metallic electrodes. In the photoelectrochemical devices and cells, SWNTs can act as an efficient charge-transport pathway suppressing the back electron transfer or as a one-dimensional nano- and meso-scaffold for assembling photoactive molecules to facilitate the charge transport through the molecule arrays. These results demonstrate that the unique optical, electrical, and structural properties of SWNTs are beneficial for developing highly efficient carbon nanotube-based photoelectrochemical devices and cells.
