- ELECTROCHEMICAL SENSOR DETECTING NITROBENZENE USING Au-Ag ALLOY NANODOTS AND METHOD OF THE SAME

摘要

The present invention relates to an electrochemical sensor for detecting nitrobenzene using Au-Ag alloy nanodots and a manufacturing method thereof. Hyaline carbon electrode surface is modified to a silicate sol-gel matrix embedded with Au-Ag alloy nanodots (SSG-AuAg NDs) to provide excellent electrocatalyst effects with respect to nitrobenzene reduction, thereby providing excellent sensor characteristics when detecting the nitrobenzene. Moreover, the silicate sol-gel matrix embedded with Au-Ag alloy nanodots of 3 nm or less can be synthesized by a single-step synthesis without using harmful reduction agents such as hydrazine, sodium borohydride, and alkyl trimethyl ammonium halide.
