Magnetic Features

Magnetic-field-accelerated photocatalytic degradation of the phenol red (PR) as a model organic pollutant was studied using rare-earth elements modified BiFeO3 (Bi1−xRxFeO3 (R = Ce, Tb; x = 0.0, 0.05, 0.10 and 0.15); BFO: RE) nanostructures. The nanostructures were prepared via the hydrothermal process and their morphological, structural, functional, optical and magnetic features were investigated in detail. The effect of magnetic fields (MFs) on photocatalysis were examined by applying the different MFs under visible light irradiation. The enhanced photodegradation efficiencies were achieved by increasing the MF up to 0.5T and reduced at 0.7T for the compositions x = 0.10 in both Ce and Tb substituted BFO. Further, mineralization efficiencies of PR, reproducibility of MF-assisted photocatalysis, stability and recyclability of BFO: RE nanostructures were also tested.

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.
