| Popis: | Conference of 2017 ISOCS/IEEE International Symposium on Olfaction and Electronic Nose, ISOEN 2017 ; Conference Date: 28 May 2017 Through 31 May 2017; Conference Code:129051; International audience; We report on the development of sensor arrays comprising synthetic boron doped diamond (BDD) electrodes modified with metal catalyst nanoparticles. The latter are deposited onto the BDD electrodes surface by a physical vapor deposition process followed by de-wetting under oxygen-free atmosphere in high temperature conditions. The mean size of the particles is in the order of 10 nm, as characterized by scanning electron microscopy (SEM) image processing and small-angle X-ray scattering (SAXS). The particles are made of e.g. platinum, iridium, gold, ruthenium or alloys thereof and showed good adhesion, and good electrochemical reactivity towards a wide range of redox analytes. Sensor arrays composed of 4 BDD electrodes each modified with a different nano-catalyst were mounted and tested for various analytical applications. For instance such a sensor array was able to detect online and discriminate the presence in tap water of the following contaminants: Imidacloprid, Dimethyl methylphosphonate (DMMP) or hydrogen peroxide, chosen for demonstration purpose. |
