Abstract

The electrochemistry of gas-generated naked Ag nanoparticles deposited on indium-tin oxide covered glass plates is compared to bulk polycrystalline Ag. The nano-specific electrochemistry has been identified and includes the preferential formation of β-oxides. In 100 mM KOH supporting electrolyte, disruption of β-oxide formation is exploited to test for the presence of diethyl cyanophosphonate. While in 8.0 M KOH, β-oxide formation is enhanced leading to testing capabilities for 2-chloroethyl ethyl sulfide. These non-redox active compounds are effective simulants for the chemical warfare agents Tabun nerve agent and sulfur mustard, respectively.
