Abstract
An effective rhodamine B (Rh B) dye sensitized Co doped TiO 2 (Co/TiO 2) materials was prepared by simple physical absorption for photocatalytic water splitting under visible light. The prepared Rh B-Co/TiO 2 materials showed a strong absorbance edge band in the range of 450-600nm (max. absorbance at 550nm) and estimated a moderate band gap of 2.58eV, which lowered than that of Co/TiO 2 (2.75eV). Rh B-Co/TiO 2 catalysts showed the high activity towards photocatalytic water splitting under visible light irradiation. The reaction with Rh B-Co/TiO 2 catalysts achieved a nearly stoichiometic evolution of H 2 and O 2 evolution of ∼227.3μmol/g-catal/h and ∼98.9μmol/g-catal/h, respectively, which is 6 times higher than that of H 2 evolution (∼37.67μmol/g-catal/h) over Co/TiO 2 catalysts. The enhanced water splitting reaction may be facilitated by the absorbed Rh B near to Co atom. This synergic effect between the Rh B and Co is crucial to the water splitting reaction.
