High-performance NH3 production via NO electroreduction over a NiO nanosheet array

Abstract

Electrocatalytic NO reduction controls NO emission and produces NH3 under ambient conditions. Herein, a NiO nanosheet array on titanium mesh is proposed as a highly active and selective electrocatalyst for NO reduction, attaining a faradaic efficiency of up to 90% with a NH3 yield of 2130 μg h−1 cm−2. Its aqueous Zn–NO battery can generate electricity with a power density of 0.88 mW cm−2 and simultaneously offer an NH3 yield of 228 μg h−1 cm−2. The NO electroreduction mechanism on NiO is revealed using theoretical calculations.
