Bismuth telluride is considered as an efficient and super-active electrocatalyst in the sector of electrochemical application. Herein, we prepared binary nanosheets (BiTe) through simple solvothermal and hydrothermal method. Furthermore, to enhance the electrocatalytic activity, graphitic carbon nitrides nanosheets (g-CN) were used to prepare the composition of BiTe/g-CN binary nanosheets (BNs) with help of hydrothermal energy. Moreover, BiTe/g-CN hybrid was characterized by various techniques (XRD, XPS, SEM, TEM, EDS and EIS analysis). The electrochemical performance of BiTe/g-CN BNs modified GCEs were analyzed by electrochemical technique (DPV, EIS and CV methods). As modified the BiTe/g-CN BNs modified electrode exhibits excellent electrochemical activity towards food toxic ractopamine (RAC) with high-sensitive and nano-molar detection limit (LOD). Besides, the practical ability was analyzed to detect the RAC in meat samples using BiTe/g-CN BNs modified GCE.
碲化铋在电化学应用领域被认为是一种高效且超活性的电催化剂。在此，我们通过简单的溶剂热和水热法制备了二元纳米片（BiTe）。此外，为了提高电催化活性，使用石墨相氮化碳纳米片（g-CN）在水热能量的帮助下制备了 BiTe/g-CN 二元纳米片（BNs）的组合物。此外，通过各种技术（XRD、XPS、SEM、TEM、EDS 和 EIS 分析）对 BiTe/g-CN 杂化进行了表征。通过电化学技术（DPV、EIS 和 CV 方法）分析了 BiTe/g-CN BNs 修饰 GCE 的电化学性能。作为修饰，BiTe/g-CN BNs 修饰电极对食品有毒莱克多巴胺（RAC）表现出优异的电化学活性，具有高灵敏度和纳摩尔检测限（LOD）。此外，使用 BiTe/g-CN BNs 修饰 GCE 分析了肉样中 RAC 的实际检测能力。
