Abstract A Cu-Fe bimetallic catalyst was prepared by immersing amidoximated PAN nonwovens into the mixed metal solution containing CuSO₄ and FeCl₃. The catalyst was characterized by X-ray photoelectron spectroscopy (XPS) and ultraviolet-visible spectroscopy (UV-vis), and then employed in the oxidative degradation of formaldehyde. The results suggested that Cu²⁺ and Fe³⁺ was immobilized onto the catalyst through coordination bonds with O-H and -NH₂ in amidoxime group, and there may exist interaction between the two kinds of metal ions through the ligands. In addition, doping Cu²⁺ make the bimetallic catalyst exhibited better catalytic activity than the monometallic Fe³⁺ catalyst in formaldehyde degradation, especially under visible light and dark state, this should be attributed to the valence state transformation between Cu²⁺ and Cu⁺ which accelerate the generation of high oxidizing Fe(Ⅳ)=O.
