摘　　要：基于绿色环保理念,以生活废弃物柚子皮为原料,通过高温碳化,制备了较大比表面积、较高导电性的生物质碳(BC),然后在BC表面负载PdCuNPs纳米颗粒,成功制备了PdCuNPs@BC复合材料。BC能够为PdCuNPs提供附着位点,并阻止PdCuNPs发生团聚,从而提升了PdCuNPs@BC的催化性能。将PdCuNPs@BC修饰于FTO电极表面,构建了用于检测Hg^(2+)的新型电化学传感器,在最佳的实验条件下,检出限为0.33μmol/L(S/N=3),线性范围在0.50~90.00μmol/L。此外评估了该传感器对自来水中Hg^(2+)检测的可行性,表现出较好的回收率。Based on the concept of green environmental protection,biomass carbon(BC)with a large specific surface area and high conductivity was prepared from household waste pomelo peel through high-temperature carbonization.PdCuNPs nanoparticles were loaded on its surface and PdCuNPs@BC composit material was successfully prepared.BC provides attachment sites for PdCuNPs and prevents aggregation of PdCuNPs,thereby enhancing their catalytic performance.A novel electrochemical sensor for detecting Hg^(2+)was constructed by modifying the surface of FTO electrode by [e-mail] optimal experimental conditions,the detection limit was 0.33μmol/L(S/N=3)and the linear range was 0.50-90.00μmol/L.In addition,the feasibility of the sensor for detecting Hg^(2+)in tap water was evaluated,showing a good recovery.
