摘要
Titanium dioxide is a wide band-gap semiconductor that can be excited to produce electron-hole pairs when irradiated with light. Such photo-induced electron-hole pairs have been utilized to generate electricity in solar cells, to split water into hydrogen and oxygen, to oxidize and degrade inorganic/organic/biological compounds in environments as well as to create superhydrophilicity. The wide solar applications and mechanisms of these photo-induced reactions are briefly reviewed in this mini review. This review would assist the readers to obtain an overview of this exciting and promising field. (C) 2013 Elsevier Ltd. All rights reserved.
