Abstract
In recent years, there have been many studies on metal/carbon hybrid materials for electrochemical applications. However, reducing the metal content in catalysts is still a challenge. Here, a facile synthesis of palladium (Pd) nanoparticle-embedded N-doped carbon fibers (Pd/N-C) through electropolymerization and reduction methods is demonstrated. The as-prepared Pd/N-C contains only 1.5wt% Pd. Under optimal conditions, bisphenolA is detected by using amperometry in two dynamic ranges from 0.1 to 10m and from 10 to 200 mu m, and the obtained correlation coefficients are close to 0.9836 and 0.9987, respectively. The detection limit (DL) for bisphenolA is determined to be 29.44 (perpendicular to 0.77)nm.
