Fabrication of TiO2 Nanotube Arrays by Electrochemical Anodization: Four Synthesis Generations

摘要: One-dimensional (1-D) nanowire and nanotube systems with high surface-to-volume ratios have been found to possess significant, useful, unique properties. The synthesis of highly ordered 1-D materials using localized chemical dissolution controlled, field-assisted oxidation reactions is particularly noteworthy for it permits achievement a precisely ordered, nanoscale self-assembly. Comparative studies show that arrays TiO2 outperform colloidal photocatalytic applications [1–5], sensing [6–9], photoelectrolysis [10–16], polymer-based bulk heterojunction photovoltaics [17–19], dye-sensitized solar cells [20–26], biofluids filtration, drug delivery other biomedical [27–30]. Initial investigations indicate they also may be useful energy storage devices such as Li-ion batteries supercapacitors; these are among those discussed in the subsequent chapters.
