Chitosan (CS) decorated reduced graphene oxide‐Ferrocene nanocomposite (RGO−Fc−CS) was synthesized by a one‐pot reaction. In the synthesis process of RGO−Fc−CS, GO−Fc was successfully self‐assembled via the π–π interaction, which had the features of large surface area and the high load. Then GO‐Fc and CS linked via one‐pot under alkaline conditions. The FT−IR, TGA, SEM were employed to characterize the successful synthesis of RGO−Fc−CS composites. A miniature electrochemical system was fabricated by RGO−Fc−CS modified glassy carbon electrode (expressed as RGO−Fc−CS/GCE) for the sensitive detection of RhB enantiomers via DPV. Electrochemical results revealed that the RGO−Fc−CS/GCE exhibited high molecular recognition toward RhB. Due to the synergy between the RGO−Fc and CS, the RGO−Fc−CS/GCE showed a linear range of 0.001–70 μM with a LOD of 0.5 nM, indicating that RGO−Fc−CS/GCE has broad application prospects to simplify monitor RhB real‐time.

壳聚糖修饰的还原氧化石墨烯-二茂铁纳米复合材料的合成及其在电化学检测若丹明B中的应用
壳聚糖（CS）装饰的还原氧化石墨烯-二茂铁纳米复合材料（RGO-Fc-CS）是通过一锅法反应合成的。在RGO-Fc-CS的合成过程中，GO-Fc通过π-π相互作用成功地自组装，具有大表面积和高负荷的特征。然后GO-Fc和CS在碱性条件下通过一锅连接。FT-IR，TGA，SEM被用来表征RGO-Fc-CS复合材料的成功合成。由RGO-Fc-CS修饰的玻碳电极（表示为RGO-Fc-CS / GCE）制成的微型电化学系统，用于通过DPV灵敏地检测RhB对映体。电化学结果表明，RGO-Fc-CS / GCE对RhB表现出较高的分子识别性。由于RGO-Fc和CS之间的协同作用，RGO-Fc-CS / GCE的线性范围为0.001-70μM，LOD为0.5 nM，
