Innentitelbild: Modulating the Electrolyte Microenvironment in Electrical Double Layer for Boosting Electrocatalytic Nitrate Reduction to Ammonia (Angew. Chem. 32/2024)

Rationally regulating the electrolyte microenvironment is an effective approach to boost the electrocatalytic nitrate reduction reaction (NO3RR) performance. In their Research Article (e202408382), Xin-Yao Yu and co-workers propose a novel strategy to enhance the NO3RR performance by mediating alkali metal cations in the electrolyte. In the presence of K+, the protons are more favorable to cross the electric double layer to reach the catalyst surface and conversion of NO3− to NO2− is promoted, thereby favoring the overall kinetics of NO3RR.
