Photocatalytic Degradation of 4-Nitrophenol by Using Porphyrin/Fe-Loaded TiO2 Composites Under Heterogeneous Photo Fenton Process

A new class of porphyrin(Pp)/Fe co-loaded TiO2 composites opportunely prepared by impregnation of [5,10,15,20-tetra(4-tert-butylphenyl)] porphyrin (H2Pp) or Cu(II)[5,10,15,20-tetra(4-tert-butylphenyl)] porphyrin (CuPp) onto Fe-loaded TiO2 particles showed high activities toward the degradation of 4-nitrophenol (4-NP) by heterogeneous photo Fenton-like processes.
