Why do some metal ions spontaneously form nanoparticles in water microdroplets? Disentangling the contributions of the air–water interface and bulk redox chemistry† Water microdroplets containing 100 μM HAuCl4 have been shown to reduce gold ions into gold nanoparticles spontaneously. It has been suggested that this chemical transformation takes place exclusively at the air–water interface of microdroplets, albeit without mechanistic insights.

Busting the Myth of Spontaneous Formation of H2O2 at the Air–Water Interface: Contributions of the Liquid–Solid Interface and Dissolved Oxygen Exposed Recent reports on the spontaneous formation of hydrogen peroxide (H2O2) at the air–water and solid–water interfaces challenge our current understanding of aquatic chemistry and have ramifications on atmosphere chemistry models, surface science, and green chemistry.
