In this study, the influences of alkali concentration, oxygen partial pressure, and temperature on the oxygen reduction reaction (ORR) were examined in detail, using a specially designed electrochemical cell, by cyclic voltammetry (CV) and linear sweep voltammetry (LSV) in NaOH solutions. It was found that the ORR pathway is dependent on the solution alkalinity, and is transformed from a two-electron reduction by forming HO2 -in dilute solutions to a one-electron reduction by forming stable O2doi:10.3866/pku.whxb201311143 fatcat:n3n7ykhx5vfqxjd42y5rfp4bm4
