英文摘要	two kinds of fe-co prussian blue analogues (fe-co pbas) with different iron valence state, fe-3[co(cn)(6)](2)center dot 12h(2)o and fe[co(cn)(6)]center dot 2h(2)o, were developed as the photo-fenton catalysts for in-depth investigation of the heterogeneous fenton reaction mechanism. these two catalysts showed exceptionally high efficiencies for the degradation of rhodamine b. the efficient redox cycling of iron species in the fe-co pbas photo-fenton process was deeply explored by mossbauer spectroscopy. the excellent photo-fenton activities of these fe-co pbas were ascribed to the existence of highly dispersed water coordinated iron sites and abundant vacancies in the metal-organic-frameworks. singlet oxygen was identified by radical scavenger experiments and electron paramagnetic resonance spectroscopy, which plays a key role in the photo-fenton process. based on these comprehensive experimental results, a novel radical reaction mechanism was proposed. this work not only opens up a new avenue for the application of fe-co pbas, but also gives a deeper insight into the mechanisms of heterogeneous fenton reactions.
