Sustainable nitrogen fixation over Ru single atoms decorated Cu2O using electrons produced from photoelectrocatalytic organics degradation

Electrocatalytic ammonia (NH3) synthesis requires electrons, usually from the oxygen evolution reaction (OER) conducted on the dark anode. To meet the thermodynamic potential of the OER and smoothly transfer charge, a high bias voltage is often required, which, however, increases energy consumption. Here, we demonstrate that using photoanode instead of dark anode can remarkably reduce the energy required. Electrons for NH3 synthesis originally...
