WebOct 9, 2024 · The central challenge of OER is to understand the mechanistic details required for efficient catalysis. The kinetics of OER are rather complicated since the metal oxide catalyses the oxygen evolution and not the metal itself. 9-11 Therefore, the catalytic activity of the electrocatalytic system can be influenced by factors like the surface and bulk … Webhydrogen electrode, we can relate the chemical potential (the free energy per H) for the reaction (H+ + e-) to that of 1/ 2H2 (eq 2 is in equilibrium). This means that, at pH ) 0inthe electrolyte and 1 bar of H2 in the gas phase at 298 K, the reaction free energies of eqs 6 and 7 are equal to those of the reverse WebThen, we briefly introduced the fundamental mechanisms and central challenges of HER, OER, ORR, CO 2 RR and NRR electrocatalysts, and highlight the theory-based efforts used to address the challenges facing these electrocatalysis processes. Finally, we propose the key challenges and opportunities of theory-driven electrocatalysis on their future. country\u0027s 意味
