Amine-modified CNFs (AN-CNFs) were first obtained through the Billups reaction from carbon nanofibers (CNFs), and were used as supports of cobalt tetracarboxylphthalocyanine (CoTCPc) for the catalytic oxidation of Acid Orange 7 (AO7) in the CoTCPc-AN-CNFs/H₂O₂ system. CNFs, AN-CNFs and CoTCPc-AN-CNFs were characterized by X-ray photoelectron spectroscopy, thermogravimetric analysis, transmission electron microscopy and N₂ adsorption-desorption. The oxidative decoloration of AO7 in the presence of CoTCPcNa-AN-CNFs and H₂O₂ was investigated by UV-Vis absorption spectra. The results showed that AO7 was oxidized efficiently in the CoTCPcNa-AN-CNFs /H₂O₂ system. The benzene ring was first introduced between CNFs and MPcs. However, its catalytic efficiency and electronic properties would not weaken. New catalytic mechanism may display in this CoTCPcNa-AN-CNFs /H₂O₂ system.
