摘　　要：By enabling the conversion of sustainably-derived electrical energy into chemical energy, electrocatalytic reactions are vital for closing the anthropogenic carbon cycle. A wide array of electrocatalytic reactions have gained extensive attention, including hydrogen evolution (HER), oxygen evolution (OER), and CO_(2) electroreduction (CO_(2)RR). However, progress in enhancing catalyst activity, selectivity, and stability is impeded by the lack of fundamental insight. Under reaction conditions, multi-step electron transfer and elementary catalytic processes convolute, influenced by the applied potential that affects the electrostatic potential of electrons through charging of the electric double layer (EDL) and/or the chemical potential of the electrocatalysts.
