- Abstract
In this work a gold electrode modified with self-assembled layers (SAMs) composed with organic S-containing compound and gold nanoparticles was prepared. The electrode with SAMs endowed with gold nanoparticles gave the high catalytic effect for ethylene glycol (EG) electrooxidation in solution at pH 7. For this novel sensor a linear relationship between the current response of EG at the potential of peak maximum ( jp) and the concentration of this compound in solution ( cEG) was found over the range 0.1 µM to 0.7 M with the detection sensitivity jp/ cEG equal to about 5 A cm−2 mol−1 dm3 (at v=0.1 V s−1) and the detection limit of 0.046 µM.
