Understanding gold nanoparticle dissolution in cyanide-containing solution via impact-chemistry
<p>The electrochemical dissolution of citrate-capped gold nanoparticles (AuNPs) was studied in cyanide (CN−) containing solutions. It was found that the gold nanoparticles exhibited different dissolution behaviours as ensembles compared to the single particles. At the single particle level, a...

| description | <p>The electrochemical dissolution of citrate-capped gold nanoparticles (AuNPs) was studied in cyanide (CN−) containing solutions. It was found that the gold nanoparticles exhibited different dissolution behaviours as ensembles compared to the single particles. At the single particle level, a nearly complete oxidation of 60 nm AuNPs was achieved at concentrations greater than or equal to 35.0 mM CN− and at a potential of 1.0 V. Mechanistic insights and rate data are reported.</p> |
