Degradation Processes

Photocatalytic degradation processes of different materials are fitted with Mittag-Leffler function and incomplete gamma function, which are response functions for Cole–Cole relaxation and Davidson–Cole relaxation. The fitting results show that both functions can fit experimental data fairly well. The order of derivative in the kinetic differential equations can be either less, or greater than one. In the case of the order of derivative is greater than one, only incomplete gamma function is reasonable for describing the photocatalytic degradation. This work further confirms the existence of the universality in photocatalytic degradation kinetics.

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.
