“…The projected crystal orbital Hamilton population (pCOHP) 36 was calculated to reveal the chemical bonding between the adsorption site and adsorbed Cl atoms. The methods mentioned above were widely adopted to explore the oxygen evolution reaction (OER), 37–39 CO 2 reduction reaction (CO 2 RR), 40–42 nitrogen reduction reaction (NRR), 43–45 nitric oxide reduction reaction (NORR), 46–48 and chlorine evolution reaction (CER), 25,26,28,49 respectively.…”
