Schematic illustration showing the reconstruction process of NiBiO2-x for boosting electrochemical NO2−RR

Caption

Under operando NO2−RR, a fraction of Bi-O in NiBiO2-x can be reduced to metallic Bi forming Ni2+-Bi0 catalytic pairs. The Ni2+ sites on NiBiO2-x can facilitate water dissociation to rapidly release protons while concurrently the neighboring Bi0 sites can promote NO2− activation to form *NO2H, synergistically boost electrochemical NO2−RR performance.
