Synthesis of PAN Fiber Supported Fe(bpy)₃²⁺ for RhB Degradation under Visible Light Irradiation

Abstract:

The amidoximated Polyacrylonitrile (PAN) fiber was applied for the support to immobilize Fe(bpy)32+ through ionic bonds, and the obtained fibrous complex was used as heterogeneous Fenton catalyst for the degradation of Rhodamine B under visible light irradiation. The results indicated that increasing Fe(bpy)32+ concentration in solution led to higher Fe(bpy)32+ content on the prepared catalysts, and the amidoxime groups helped greatly for the immobilization of Fe(bpy)32+ via coordination effect. This catalyst exhibits an obvious absorption in the visible region and could effectively degrade Rhodamine B in the presence of H2O2 under visible light irradiation. In addition, no deactivation of the catalyst was observed even after five consecutive runs of dye degradation.
