Preparation of Phthalocyanine-Modified Mesoporous Titania and Its Visible-Light Photocatalytic Activity

LI Xiaopei, CHEN Feng*, ZHANG Jinlong(Laboratory for Advanced Materials, Institute of Fine Chemicals, East China University of Science and Technology, Shanghai 200237, China)  
Mesoporous titania was successfully prepared by the soft-template method. The low angle XRD pattern and BJH pore distribution indicated that the pores of mesoporous titania were well ordered and had a average pore diameter of 4.75 nm. Cu(Ⅱ)-tetracarboxyphthalocyanine (CuPcTc)-sensitized mesoporous titania (CuPcTc-TiO2) photocatalyst samples were prepared by adsorption of CuPcTc on the surface of mesoporous titania. Under the irradiation of visible light (λ550 nm), CuPcTc-TiO2 showed high photocatalytic activity for the degradation of fluorescein and had optimum visible-light activity when the CuPcTc adsorption amount was 4% in mass fraction. In addition, CuPcTc-TiO2 exhibited higher visible-light photocatalytic activity than CuPcTc-sensitized P25 (CuPcTc-P25) for the degradation of fluorescein.
