| Abstract |
Efficient, stable, and low-cost electrocatalysts for the degradation and sensing of environment pollutants are essential components of clean environment monitoring. Here we report, one-step synthesis and characterization of 1-3 nm diameter sized bi-metallic AuAg nanodots (NDs) embedded in amine functionalized silicate sol–gel matrix (SSG) and its electrochemical studies toward nitrobenzene. The SSG was used as a reducing agent as well as stabilizer for the prepared mono- and bi-metallic nanoparticles (NPs). From the HRTEM, STEM-EDS and XPS analyses, the bi-metallic AuAg NDs were identified as an alloy and not the mixtures of Au and Ag NPs. The AuAg alloy NDs with different concentrations of Au and Ag modified electrodes exhibited synergistic electrocatalytic effect than did the Au and Ag NPs towards nitrobenzene reduction and detection. |
