Boosting nitrite conversion to ammonia by rational design of a Cu2O-based electrocatalyst

Abstract

A ruthenium-doped Cu₂O electrocatalyst with a multi-layered hollow spherical structure has been proposed for efficient nitrite conversion to ammonia through electrocatalysis. The unique structure provides nanoconfinement effects, which, together with the tailored electronic properties, synergistically contribute to the reduced energy barriers, resulting in high electrocatalytic efficiency and NH₃ selectivity.
