Photocatalysis and Immobilization of Nanosized Titanium Dioxide

Nanosized titanium dioxide is widely used in environmental and material fields such as waste water treatment,air puriffication and antibacteria and self-purification of material surfaces because of its photocatalysis.It is very important to immobilize the photocatalysis onto substrates.This paper is a review about the immobilizations of nanosized titanium dioxide photocatalysis,including immobilization methods,immobilization mechanisms and their qualification.
