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 1.5 wt % Pd. Under optimal conditions, bisphenol A is detected by using amperometry in two dynamic ranges from 0.1 to 10 μm and from 10 to 200 μm, and the obtained correlation coefficients are close to 0.9836 and 0.9987, respectively. The detection limit (DL) for bisphenol A is determined to be 29.44 (±0.77) nm.

用于电化学传感的钯纳米粒子嵌入N掺杂碳纤维的简便合成。

近年来，对用于电化学应用的金属/碳杂化材料进行了许多研究。但是，降低催化剂中的金属含量仍然是一个挑战。在这里，展示了通过电聚合和还原方法轻松合成嵌入钯（Pd）纳米粒子的N掺杂碳纤维（Pd / NC）。所制备的Pd / NC仅包含1.5重量％的Pd。在最佳条件下，使用安培法在0.1至10μm和10至200μm的两个动态范围内检测双酚A，获得的相关系数分别接近0.9836和0.9987。双酚A的检出限（DL）确定为29.44（±0.77）nm。
