A promising fabrication strategy used for designing TiO2 photocatalysts, which enhanced the photocatalytic activity by combining TiO2 with a new carboxyl-group-containing Cu(II) porphyrin (CuPp) in a sol-gel processing TiO2 and a one-pot solvothermal condition, has been proposed. Both porphyrins and composite photocatalyst CuPp-TiO2 have been characterized by spectroscopic techniques. Their photocatalytic performances were investigated by testing the photodegradation of 4-nitrophenol (4-NP) in aqueous solution under UV-vis light irradiation. The results reveal that the methodology for the anatase TiO2 photocatalyst is easy to achieve, and the photocatalytic activity measurements illustrate that the Cu(II) porphyrin-based TiO2 photocatalyst we synthesized displays superior photocatalytic activity and good chemical stability for organic pollutant photodegradation due to the strong interactions between Cu(II) porphyrins and TiO2.
