提出了一种利用常压下化学气相沉积技术设计的金属氧化物纳米结构。由于纳米结构的优势之一是其相对较大的比表面积，因此催化剂被认为是很好的应用之一。在本研究中，利用染料敏化锐钛矿组装了光电化学电池，以证实纳米结构的应用。锐钛矿多晶薄膜的厚度为4-8微米，由晶体颗粒构成的柱状结构组成，其中几个颗粒的尺寸为∼100 nm。光敏剂Ru(4，4‘-二羧基-2，2’-联吡啶)2(NCS)2(Ru(Dcbpy)2(NCS)2)牢固地附着在锐钛矿表面，然后组装成光电化学电池。光能转换效率为3.96%。
A nanoarchitecture of metal oxide designed by a chemical-vapor-deposition technique operated under atmospheric pressure is proposed. As one of the advantages of the nanoarchitecture is its relatively large surface area, the catalyst is thought to be one of good applications. In this study, a photoelectrochemical cell utilizing dye-sensitized anatase was assembled to confirm application of nanoarchitechture. The anatase polycrystalline film, 4–8 µm in thickness, is composed of columnar structures constructed by crystalline particles, several being ∼ 100 nm in size. The photosensitizer, Ru(4,4′-dicarboxy-2,2′-bipyridine)2(NCS)2 (Ru(dcbpy)2(NCS)2), adheres to the anatase surface firmly, followed by the assembly of the photoelectrochemical cell. A sunlight-to-electrical energy conversion efficiency of 3.96% was observed.
