Boosting Seawater Desalination by Ampere‐Level Nitrate Electroreduction On Defect‐Rich Ultrathin RuCu Alloy Nanostructures

open access: yesAdvanced Materials, EarlyView.
Defect engineering of ultrathin RuCu alloy nanostructures has been successfully achieved to enhance ammonia electrosynthesis under indutrial‐level current density. Simultaneously, the stable ampere‐level operation of nitrate electroreduction on defective RuCu nanostructures can drive seawater desalination at an ultrafast salt removal rate, offering an ...
