摘　　要：本文通过一种简单的水热反应合成出核壳型纳米材料Ag@C,然后再利用Ag@C表面丰富的功能基团均匀地负载一层Ag纳米颗粒,得到了大小均一、形貌良好的三层Ag@C@Ag核壳型纳米材料。实验结果表明,该Ag@C@Ag核壳纳米材料对邻苯基苯酚的电化学测定有良好的催化活性。据此,成功构建了一种简单、快速检测邻苯基苯酚的新型电化学传感器。该电化学传感器测定邻苯基苯酚的线性范围为0.08-35μmol/L,检出限为13.6nmol/L。In this paper,we first synthesized core-shell nano material Ag@C by a simple hydrothermal reaction,and then used the functional groups of Ag@C surface to load a layer of Ag nanoparticles evenly,and got the Ag@C@Ag three core-shell nano material with uniform size and good morphology.The results showed that the synthesized Ag@C@Ag core-shell nano composite had a good electrocatalytic activity to o-phenyl phenol.According to the result,we have successfully constructed a simple,novel electrochemical sensor for rapid detection of o-phenyl phenol.The linear range was 0.08-35μmol/L,and the detection limit（S/N=3）was 13.6nmol/L.
