摘要：

Nitrogen-doped carbon (NC) materials were prepared by pyrolyzing pyrrole in the presence of basic magnesium carbonate at 400-700 degrees C. Three kinds of C-N bonding patterns, namely pyridinic-, pyrrolic-, and graphitic-type N, are present in NC products. The pyrolysis temperature has an intensive influence on the contents of three nitrogen species. It is found that NC-700, containing the highest content (3.87 at %) of graphitic-type N, exhibits the best discrimination ability for ascorbic acid (AA), dopamine (DA), and uric acid (UA). Differential pulse voltammetry study reveal that the detection limit (S/N=3) can reach 0.090 mu M for DA even in the presence of 1000 mu M AA and 200 mu M UA. (C) 2013 Elsevier B.V.
