Abstract
Abstract The sensitized photocatalytic oxidation (SPCO) of the herbicide terbutryne using tris(bipyridyl)ruthenium complexes as sensitizer and titanium dioxide as semiconductor was investigated. Tris(4,4′-dicarboxy-2,2′-bipyridyl)ruthenium(II) chloride is an excellent sensitizer, and on exposure to sunlight complete degradation of the pollutant occurs. The thermodynamic and kinetic requirements for successful SPCO are discussed. The adsorption of the components on the semiconductor surface, electron transfer and electron back transfer determine the efficiency of the process.
