WebAug 17, 2024 · The sharp decrease of current efficiency at −1.0 V indicates an increasing portion of side reactions, such as hydrogen evolution, hydrogen peroxide reduction, or four-electron oxygen reduction (24, 25). These side reactions can be facilitated by excessive H + (26, 27), but the initial step of ORR to H 2 O 2 on PEDOT does require H + . WebDec 25, 2015 · Hydrogen peroxide is decomposed as follows: 2 H X 2 O X 2 2 H X 2 O + O X 2. This is a disproportionation redox reaction of H X 2 O X 2 involving the 2 half reactions. H X 2 O X 2 O X 2 + 2 H X + + 2 e X −. H X 2 O X 2 + 2 e X − + 2 H X + 2 H X 2 O. But I noticed semantically that it can also be the sum of the two following half reactions:
