摘要：

In this paper, carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) functionalized with polyethylenimine (PEI) was prepared and a glassy carbon electrode (GCE) modified with the above nanocomposites (denoted as PEI-MWCNTs-COOH/GCE) was fabricated. Using p-nitrophenol (p-NP) and o-nitrophenol (o-NP) as model compounds, the electrocatalysis of the modified electrode was studied. The results show that the sensitivity and selectivity of the modified electrode are significantly improved due to the synergistic effect of MWCNTs-COOH and PEI. The oxidation peak potentials of o-NP and p-NP were sep...
