Magnetite/Iron Foil as an Effective and Nonfiltration Catalyst for Heterogeneous Fenton-like Reactions under Neutral Conditions.

A magnetite/iron foil (MIF) composite was synthesized as a heterogeneous Fenton-like catalyst. The MIF catalyst effectively degraded Rhodamine B under neutral conditions (degradation efficiency = 86%), avoiding the procedure of pH adjustment. The MIF catalyst could be conveniently recycled without filtration, and the advantages of the stability and reusability of a MIF catalyst made it promising in practical wastewater treatment.
