Evaporation‑Driven Electrostatic Amplification in Charged Microdroplets as a Supplemental Pathway in Gas‑Evolving Electrolysis

This work explores how evaporation‑driven charge concentration in microdroplets can amplify electrostatic potentials during gas‑evolving electrolysis. As solvent evaporates, the droplet’s surface charge density increases, creating transient high‑field regions capable of enhancing ion emission, promoting localized discharge events, and influencing gas evolution pathways. The study outlines a supplemental electrostatic mechanism that operates alongside conventional Faradaic processes, offering a new perspective on microdroplet behavior in electrochemical environments. The findings highlight how charged microdroplets may contribute to unexpected reaction pathways, enhanced ion release, and nonlinear amplification effects in electrolysis systems.
