Abstract

This article describes the multifunctional applications of TiO2. It substantiates the universality of the anodization process to grow well-ordered TiOxnanotube (T–NT) of hollow cylindrical shape on a variety of planar and nonplanar substrates. It highlights an approach to effectively bring down the cost of anodization via utilization of a small volume of electrolyte. The multifunctionality of these nanostructures is highlighted through representative examples that illustrate wide ranging optical, electronic, and catalytic properties. Combining the T–NT with other materials such as metals and photoactive additives to form composite nanostructures has been shown to benefit photocatalysis, photovoltaics, biological processes, and environment-related applications. This article also demonstrates the applicability of T–NT as an agent to produce dissolved oxygen in simulated blood—an application that can assist in the development of artificial lungs. Key results from the research group, collaborations, and recent articles are highlighted.
