摘要：

Single-atom catalysts (SACs) containing noble metals have been largely explored for various catalytic reactions and demonstrated high activity and chemical stability but are rarely used for electrocatalytic nitrate reduction to ammonia (NO3-RA) because of their strong tendency towards hydrogen evolution reaction (HER). Herein, we developed the N, O trans-coordination strategy to inhibit the HER of carbon nanotube-based Ag SACs (Ag1/ NOCNT) catalyst, thus improving the NH3 production. The Ag1/NOCNT exhibits a record-high ammonia yield rate (YRNH3) of 90 mol h-1 gAg-1, more than two folds of the...
