Abstract

Titania was modified by macrocyclic complexes using a new in situ chemical synthesis strategy. Metal phthalocyanine (MPc) was synthesized during TiO₂ gel synthesis and nanocatalyst MPc-TiO₂ with particle size of less than 15 nm was obtained as well. The catalysts were characterized by UV-VIS, DRS, FT-IR and XRD to verify the loading of metal phthalocyanine. The dopping of metal phthalocyanine narrowed the band-gap of TiO₂ and it was responsive to visible light irradiation, the as synthesized CoPc-TiO₂ heated at 300 ºC showed band gap energy of 1.84 eV. The as-prepared MPc-TiO₂ catalyst can be applied in the photocatalytic reduction of CO₂ under visible light, giving the yield of formic acid of 2863.3 μmol/g-catal. after 10 h of reaction. The photosensitivity of CoPc and ZnPc were better than that of NiPc. The electron density of cobalt was higher so it was beneficial to the election transformation from excited CoPc to the conduction band of TiO₂. The photo-efficiency is greatly increased.
