Uniform silver shell formation for air-stable Cu@Ag NW coatings with enhanced conductivity

Copper@silver (Cu@Ag) core–shell nanowires (NWs) were synthesized using a controlled galvanic displacement approach designed to suppress the oxidation typically observed in copper nanostructures. The procedure included a Diethylhydroxylamine (DEHA) based pretreatment to remove na...

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO 2 Reduction

ABSTRACT Pulsed electrolysis and Cu‐Ag tandem catalysis are both promising strategies for electrochemical CO 2 reduction, yet their interplay remains unclear. Here, we show that pulsed operation does not preserve the as‐prepared Cu‐Ag catalyst and instead generates a dynamic bime...
