High-concentration Organic Dye Removal Using Fe2O3•3.9MoO3 Nanowires as Fenton-like Catalysts

Abstract

In past few years, nanomaterials have shown a great potential for organic waste water treatment. Herein we report the single-step ligand-free synthesis of Fe2O3 •nMoO3 composites with different morphologies, including nanowires, bowknot-like microstructures, and urchin-like microstructures, through an oriented-attachment mechanism. It is the first time that the Fe2O3 •3.9MoO3 nanowires were synthesized successfully with tunable lengths from 5.1 µm to 37.4 µm as an efficient and recyclable Fenton-like catalyst for Congo red. 97.7% of degradation efficiency within 60 min and 0.0085 L/(mg•min) of kinetic constant ccording to second order kinetic reaction equation were achieved. Degradation capacity for 250 mg/L of Congo red is up to 231.4 mg/g, which shows excellent degradation ability at high dye concentration. The Fe2O3 •3.9MoO3 nanowires hold great potential for organic pollutant removal.
