Visible light photocatalytic activity induced by the carboxyl group chemically bonded on the surface of SrTiO3

Applied Catalysis B: Environmental 102 (2011) 286–290

Nanocrystals of cubic perovskite SrTiO3 chemically adsorbed
carboxyl group on the surface could be synthesized by microwave assisted
solvothermal reactions in KOH methanol-oleic acid
solutions using Ti(OC3H7)4 and SrCl2·6H2O. The functional group
(–COO−) of oleic acid chemically bonded on the surface generated
new absorption in the visible region and induced visible light
responsive photocatalytic activity.
