Single‐Atom Cu Catalysts: Single‐Atom Cu Catalysts for Enhanced Electrocatalytic Nitrate Reduction with Significant Alleviation of Nitrite Production (Small 49/2020)

In article number 2004526, Chunhua Feng and co-workers demonstrate that Cu catalysts minimized at the single-atom level can overcome the limitations of nanoparticles and bulk materials in nitrate reduction reaction (NO3RR). These catalysts anchored on nitrogenated carbon nanosheets exhibit outstanding activity and stability for NO3RR and distinctly suppress the release of nitrite intermediate due to the favorable adsorption of NO3− and NO2−.
