H-transfer is promoted in aqueous electrolyte. The salt
additives’ effects were considered from the aspects of the anions and cations. The anions of salts in Area 1 could provide more active sites for H adsorption and transfer . The cations, together with
their anions, could change the chemical environment of the OH group in the electrolyte, and promote
H-transfer . Lower degradation is closely related to the improvement in the amount of H carriers
and the H-transfer process
