Abstract
The preparation and photocatalysis of colloidal titania modified with Ru(2, 2'-bipyridyl)(3)(2+)- grafted polyacrylate were investigated. Visible light irradiation of the Ru(2,2'-bipyridyl)(3)(2+)-tethered titania in pH 7.0 bu ffer solution gave electron transfer to methyl viologen to form the cation radical via electron migration from the Ru(II) complex to the titania surfa ce.
