Tandem amorphization and bismuth-doping modulate the interfacial electronic structure of cobalt sulfide for efficient nitrate-to-ammonia electroreduction.
Electrocatalytic nitrate reduction (NO3RR) offers a sustainable route for ammonia synthesis but is hampered by the competing hydrogen evolution reaction (HER) and sluggish intermediate conversion at the catalyst-electrolyte interface. Herein, we report an amorphous Bi-doped cobalt sulfide (a-Bi-CoS) catalyst that addre...
