Since the first discovery of photocatalytic water splitting on a TiO2 electrode under ultraviolet (UV) light, TiO2 materials have been widely investigated over the past few decades due to their unique properties such as nontoxicity, abundance, easy availability, and stability. For the moment, TiO2 materials present great potentials in the applications from the conventional areas (e.g., pigment, cosmetic, and toothpaste) to the latest developed areas including catalysis, energy storage and conversion, biomedicine, environmental remediation and so on. Beyond all question, TiO2 materials render new candidates to overcome the energy, environment, and health challenges facing humanity today.
