Overall, R9 followed by R10 would not produce current. However, our calculations show that in the presence of water, O2* is even more negatively charged with a population of -1.1e and forms strong hydrogen bonds. With the singlet desorption path as prohibitive as shown in Figure and the association channel blocked at high electrode potential, O2* could only follow the 4e -ORR pathway, through O2* dissociation, OH* formation and OH* desorption, all of which are quite facile, even up to 1.2 V RHE.
