Abstract

Photocatalyst cobalt phthalocyanine loaded on titania (CoPc/titania) has been prepared by an advanced sol-gel method with titanium tetrabutoxide as precursor, to extend the optical absorption of TiO₂ from UV to visible region. Carbon dioxide is reduced to HCOOH, CH₃OH, HCHO, CO and CH₄ in caustic solution under visible light irradiation and photocatalyzed by CoPc/titania. The total yield of the photocatalytic products can reach 406.65 μmol/g(cat.) after 10 hours of irradiation, and the main product, HCOOH can reach 355.82 μmol/g(cat.).
