ABSTRACT
Electrocatalytic NO reduction is regarded as an attractive strategy to degrade the NO contaminant into useful NH3 , but the lack of efficient and stable electrocatalysts to facilitate such multiple proton-coupled electron-transfer processes impedes its applications. Here, we report on developing amorphous B2.6 C supported on a TiO2 nanoarray on a Ti plate (a-B2.6 C@TiO2 /Ti) as an NH3 -producing nanocatalyst with appreciable activity and durability toward the NO electroreduction. It shows a yield of 3678.6 µg h-1 cm-2 and a FE of 87.6 %, superior to TiO2 /Ti (563.5 µg h-1 cm-2 , 42.6 %) and a-B2.6 C/Ti (2499.2 µg h-1 cm-2 , 85.6 %). An a-B2.6 C@TiO2 /Ti-based Zn-NO battery achieves a power density of 1.7 mW cm-2 with an NH3 yield of 1125 µg h-1 cm-2 . An in-depth understanding of catalytic mechanisms is gained by theoretical calculations.
