Abstract: A novel heterogeneous catalyst, amorphous Cu0 on the carbon nanofibers was developed and characterized by means of several characterization techniques. The prepared Cu0 was investigated as a heterogeneous catalyst for N-arylation reaction. The results show it is an excellent catalyst with recyclability, high consistency and catalytic activity. After the catalyst was used for 5 cycles in the N-arylation reaction, amorphous Cu0 reunited into crystalline copper nanoparticles with different particle sizes and its good heterogeneity in the catalytic system was confirmed after the catalyst recovery.

Key words: Amorphous Cu, Carbon nanofiber, N-Arylation reaction
