Photoinduced electron transfer catalysis of titania particles modified with a Ru(2,2'-bipyridyl)3 -grafted polymer by visible light

The preparation and photocatalysis of colloidal titania modified with Ru(2,2'-bipyridyl)3 -grafted polyacrylate were investigated. Visible light irradiation of the Ru(2,2'-bipyridyl)3 -tethered titania in pH 7.0 buffer solution gave electron transfer to methyl viologen to form the cation r...

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