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.
