Significant Application

The photocatalytic degradation of methylene blue (MB) under visible light irradiation is investigated by using the TiO2photocatalyst sensitized with meso-tetra (4-carboxyphenyl) porphyrin (H2TCPP) and/or meso-tetra (4-carboxyphenyl) copper porphyrin (CuTCPP). The XRD and XPS experimental results indicate that porphyrins are chemisorbed on the surface of TiO2through the O=C-O-Ti chemical bond. The degradation of methylene blue (MB) by H2TCPP and/or CuTCPP sensitized TiO2and under incandescent lamp irradiation is likely through injecting electrons from the photoexcited sensitizer to the conduction band of TiO2. The porphyrin-and/or metallic porphyrin-sensitized TiO2exhibits higher absorbability in the visible-light region than pure TiO2. All facts show that the porphyrin-, and/or metallic porphyrin-sensitized TiO2have potentially a significant application in wastewater treatment.
