Preparation and Characterization of Conjugated Microspheres FeTCPP-SSA-TiO₂

Abstract:

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.
