High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.
