| 英文摘要 | the non-aqueous li-air (o-2) battery has attracted intensive interest because it can potentially store far more energy than todays batteries. presently li-o-2 batteries suffer from parasitic reactions owing to impurities, found in almost all non-aqueous electrolytes. impurities include residual protons and protic compounds that can react with oxygen species, such as the superoxide (o-2(-)), a reactive, one-electron reduction product of oxygen. to avoid the parasitic reactions, it is crucial to have a fundamental understanding of the conditions under which reactive oxygen species are generated in non-aqueous electrolytes. herein we report an insitu spectroscopic study of oxygen reduction on gold in a dimethyl sulfoxide electrolyte containing phenol as a proton source. it is shown directly that o-2(-), not ho2, is the first stable intermediate during the oxygen reduction process to hydrogen peroxide. the unusual stability of o-2(-) is explained using density functional theory (dft) calculations. |
