Inside Cover Picture: Modulating the Electrolyte Microenvironment in Electrical Double Layer for Boosting Electrocatalytic Nitrate Reduction to Ammonia

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.
