Preparation and Characterization of Conjugated Microspheres FeTCPP-SSA-TiO2

The novel photocatalyst (FeTCPP-SSA-TiO2) with chemical bond linking sensitized was successfully designed and fabricated. As bridging unite, sulfosalicylic acid (SSA) was used for grafting active functional groups onto TiO2 surface thereby improving the adhesion strength between trtra-carboxyphenyl porphyrin iron (FeTCPP) and TiO2. The morphology and structure of the photocatalyst was characterized. Finally, photocatalytic properties of the prepared samples have been investigated by the degradation of methylene blue (MB). The results indicated that FeTCPP-SSA-TiO2 possessed enhanced photocatalytic performance and long-term stability over four recycles.
