Carbon Encapsulated FeCu4 Alloy Nanoparticles Modified Glass Carbon Electrode to Promote the Degradation for P-Nitrophenol

The electrochemical redox of p-nitrophenol was carried out with bare glassy carbon electrode modified by carbon encapsulated FeCu4 alloy nanoparticles by cyclic voltammetry. The reductive peak potential was positively moved and the value of redox peak currents were increased compared to the based on bare GCE. The conditions of the scan rate and the stability were also discussed. Through the cyclic voltammograms, we can know that the catalytic activity of the FeCu4/C nanoparticles increased with increasing the scanning rate in the range from 50 to 100 mVs(-1). The results indicated that the bare GCE modified with FeCu4/C demonstrated perfect catalytic activity and stability for the degradation of p-NP.
