Titanium Dioxide Nanomaterials

Abstract As a versatile material of photocatalytic properties, low cost, good biocompatibility, and high chemical stability, titanium dioxide (TiO 2 ), especially at the nanometer scale, have been investigated extensively and intensively in applications from energy and environment to health. To date, various preparation methods have been developed to synthesize TiO 2 nanomaterials with well‐controlled shape (e.g., nanorod, nanowire, and nanotube) and desired properties. This article briefly introduces the up‐to‐date developments of TiO 2 nanomaterials. It focuses on their synthesis and also covers their properties, modifications, and applications.
