摘要：
The photocatalytic degradation of Rhodamine B(RhB) on TiO2 nanoparticle modified with porphyrin (Pr) and Fe(III)porphyrin (Fe(III)Pr), which were prepared through the chemisorption method, have been investigated under ultraviolet light and visible light irradiation. The results indicated that the photodegradation of RhB was significantly enhanced in the presence of the Pr/TiO2 or Fe(III)Pr/TiO2 comparing with the nonmodified TiO2 under ultraviolet light, but under visible light. only Pr/TiO2 has remarkable effect.
