TLDR
A review of the current progress in the area of TiO 2 photocatalysis, mainly photocatalytic air purification, sterilization and cancer therapy is discussed in this article.Abstract:
Abstract Scientific studies on photocatalysis started about two and a half decades ago. Titanium dioxide (TiO 2 ), which is one of the most basic materials in our daily life, has emerged as an excellent photocatalyst material for environmental purification. In this review, current progress in the area of TiO 2 photocatalysis, mainly photocatalytic air purification, sterilization and cancer therapy are discussed together with some fundamental aspects. A novel photoinduced superhydrophilic phenomenon involving TiO 2 and its applications are presented.read more

Synergistic Effect in Photocatalysis As Observed for Mixed-Phase Nanocrystalline Titania Processed via Sol−Gel Solvent Mixing and Calcination
Ajesh K. Zachariah,K. V. Baiju,Satyajit Shukla,K. S. Deepa,J. James,Krishna Gopakumar Warrier +5 more
TL;DR: In this paper, the photocatalytic activity of mixed-phase nanocrystalline titania (TiO 2) processed via sol−gel SMC is measured by monitoring the degradation of the methylene blue dye in an aqueous solution, under UV-radiation exposure, using the UV−vis absorption spectroscope.

Template-Free Fabrication of TiO2 Hollow Spheres and Their Photocatalytic Properties
TL;DR: The as-prepared TiO(2) hollow nanostructures exhibited good photocatalytic activity for the degradation of phenol and may include the hydrolysis of Ti(IV) with the water formed from the solvothermal etherification reaction, the aggregation of the anatase TiO (2) nanoparticles, and the Ostwald ripening.
