Bi/ZIF-8 catalysts: the important role of ZIF-8 for enhanced electrochemical N2-to-NH3 conversion using a neutral electrolyte

The introduction of ZIF-8 not only contributed to the adsorption of N 2 and the exposure of active sites but also promoted the generation of electron-rich Bi. Further, the electron-rich Bi enhance the adsorption and activation of N 2 .
