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

Photo-catalytic degradation of toxic dye amaranth on TiO2/UV in aqueous suspensions
Vinod Kumar Gupta,Rajeev Jain,Alok Mittal,Tawfik A. Saleh,Arunima Nayak,Shilpi Agarwal,Shalini Sikarwar +6 more
TL;DR: The photo-catalytic degradation of an azo dye - Amaranth (AM) - has been investigated in TiO(2)/UV aqueous suspensions and it was observed that decolorization rate increased by the increase in temperature and the lower the pH the higher the degradation.

Electrochemical Photolysis of Water at a Semiconductor Electrode
Akira Fujishima,Kenichi Honda +1 more
TL;DR: Water photolysis is investigated by exploiting the fact that water is transparent to visible light and cannot be decomposed directly, but only by radiation with wavelengths shorter than 190 nm.
