Nano-spatially confined Pd–Cu bimetals in porous N-doped carbon as an electrocatalyst for selective denitrification

Nanodenitrification is achieved by bimetallic Pd–Cu nanoparticles encapsulated in porous N-doped carbon as electrocatalysts, with reduced nitrate below drinking water standards and a N₂ selectivity as high as 83% in a neutral electrolyte.
