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.
