摘要

A novel BiPO4/NH2-MIL-53(Fe) composite was synthesized through solvothermal method. Photocatalytic performances of the synthesized composites were evaluated by removal of tetracycline hydrochloride (TCH) and Indigo Carmine (IC) pollutants under visible light irradiation. It was revealed that BiPO4/NH2-MIL-53(Fe) composites displayed better photocatalytic performance than pure BiPO4 and NH2-MIL-53 (Fe) catalysts individually. Among the composites optimal ratio is 3:1 of BiPO4/NH2-MIL-53(Fe) (BPM-1) exhibits the highest photocatalytic activity which is 80% and 94% removal of TCH and IC within 2 h. The enhancement in the photocatalytic activity is because of the more efficient visible light absorption and effective charge separation that makes the photo degradation process easier. The electrochemical impedance results of BPM-1 substantiated the reduction in there combination of electron-hole pairs in comparison to the bare materials. The composite also showed better catalytic reduction efficiency for 4-nitrophenol reduction. Recyclability test validates the better photochemical stability and reusability of BPM-1. This work will provide a new path to design and fabricate composite photocatalysts based on the metal organic framework for various pollutants degradation and reduction applications.
