Abstract
Silver nanoparticles were synthesized by reducing [Ag(NH3)2]+ at a gas/liquid interface in the presence of silver seeds. Transmission electron microscopy (TEM) observations reveal that the size of these silver nanoparticles is around 35–40nm with the average particle size of 37nm. The silver nanoparticles were applied for the electrochemical sensor and electrochemical investigations indicate that the nanoparticles possess an excellent performance toward H2O2. The linear range is estimated to be from 5.0μM to 4.0mM with a low detection limit of 1.7μM, a sensitivity of 166.7μAmM−1cm−2 and a response time of 3s. Additionally, the sensor exhibits good anti-interference.
