摘要：
Iron(H)-tetra-(5,6-dichloro-1,4-dithin)-porphyrazine (abbreviated as FePz(dtnCl(2))(4)) was found to exhibit a strong absorption in the visible range when dissolved in water. It could thus be used as a novel photocatalyst for activating, molecular oxygen in air to degrade Rhodamine B under visible light irradiation. It showed efficient catalytic activity in aqueous solution or supported on CG400 ion-exchanged resin. The behavior of the supported FePz(dtnCl(2))(4) was studied by UV-VIS reflectance spectroscopy and X-ray photoelectron spectroscopy (XPS). The specific enhanced effect between FePz(dtnCl(2))(4) and CG400 resin was determined. The catalyst could be recycled and reused with little loss in activity for 10 runs in the heterogeneous system.
