Abstract
Abstract The electrochemical nitric oxide reduction reaction (NORR) holds a great potential for removing environmental pollutant NO and meanwhile generating high value-added ammonia (NH 3 ). Herein, we tactfully design and synthesize a ternary Co/Co 3 O 4 /CoB heterostructure that displays a high NH 3 Faradaic efficiency of 98.8% in NORR with an NH 3 yield rate of 462.18 µmol cm −2 h −1 (2.31 mol h −1 g cat −1 ) at −0.5 V versus reversible hydrogen electrode, outperforming most of the reported NORR electrocatalysts to date. The superior NORR performance is attributed to the enhanced charge and proton transfer over the ternary Co/Co 3 O 4 /CoB heterostructure. The charge transfer between CoB and Co/Co 3 O 4…
