Abstract

The slow conversion of Fe(Ⅱ)/Fe(III) cycle was largely limited the degradation efficiency of many photo-Fenton systems. Herein, four Fe-MOFs nanorods (namely Fe-TCPP-1, Fe-TCPP-2, Fe-TCPP-3, Fe-TCPP-4) with decreasing length-diameter ratios were synthesized in a household microwave oven, using photosensitizer porphyrin and iron ions with Fenton activity as building blocks. Among them, the Fe-TCPP-3 exhibited high photogenerated electron-hole (e^--h⁺) separation efficiency and largest pore structure, endowing Fe-TCPP-3 with superior photo-Fenton property. In addition, Fe-TCPP-3 based photo-Fenton system was applied to efficiently degrade antibiotic ciprofloxacin (CIP) under neutral condition, due to the continuously generated reactive species (h⁺, e^-, OH^·, O₂^·-, ¹O₂) in Fe-TCPP-3 under visible-light irradiation. With irradiation for 30 min, the degradation efficiency of the system could reach about 73 %, which was about 26-fold towards the system without light irradiation. This study paved a way to modulating the photo-Fenton activity of MOF-based catalysts.
