In situ observations of gold deposition in a dense liquid layer at the pyrite–water interface

Proceedings of the National Academy of Sciences, Volume 123, Number 4, January 2026.
SignificanceThe adsorption and reduction of gold ions on pyrite surfaces causes the formation of gold nanoparticles (AuNPs) and induces efficient precipitation of gold. However, the nucleation mechanisms and growth kinetics of AuNPs at the pyrite-water level…
