提出了一种简便、一锅法、环境友好的利用胡椒生物质作为还原剂和稳定剂制备银（Ag）纳米粒子的方法。从干燥的胡椒叶提取物中制备的银纳米颗粒具有独特的球形结构和面心立方结构，具有优选的（111）取向。所制备的Ag/GCE传感器对NO2-的氧化表现出优异的电催化活性，响应时间快，灵敏度高，检测下限分别为10 s，1642.27 μ AmM-1 cm（-2）和0.046 μ M。此外，构建的传感器具有长期稳定性和优异的抗干扰性能，为生物介导的纳米催化剂在电化学传感器中的应用铺平了新的方向。(C)2015年韩国工业与工程化学学会。Elsevier B. V.出版，保留所有权利。
A facile, one-pot and environmental benign method exploiting Piper betle biomass as a reducing and stabilizing agent was proposed for the preparation of silver (Ag) nanoparticles. The Ag nanoparticles prepared from dried Piper betle leaves extract exhibited unique spherical configuration and facecentered-cubic structure with preferred (1 1 1) orientation. The fabricated Ag/GCE sensor exhibited an exceptional electrocatalytic activity toward NO2- oxidation with a quick response time, high sensitivity and lower detection limit of 10 s, 1642.27 mu AmM-1 cm(-2) and 0.046 mu M, respectively. Furthermore, the constructed sensor exhibited long-term stability and excellent anti-interference properties, paving new dimensions for the utilization of bio-mediated nanocatalysts in electrochemical sensors.
