Driving reversible redox reactions at solid –liquid interfaces with the electron beam of a transmission electron microscope

This study demonstrates that the flux of electrons in the beam used to acquire TEM images allows switching the oxidising or reducing nature of the solution. High electron fluxes favour reduction reactions leading to the deposition of metallic copper, whereas low electron fluxes favour oxidising redactions inducing metal dissolution. The chemical and electronic processes possibly involved in these tunable redox reactions are qualitatively discussed together with their possible impacts on other LCTEM experiments.
