Abstract
Successive one-electron reductions of molecular oxygen yield the superoxide radical (O2-) H2O2, the hydroxyl radical (OH) and water. Redox potentials at pH 7 for one-, two- and four-electron couples involving these states are presented as a potential diagram. The significance of each of these potentials is explained. The complete potential diagram enables complex systems to be rationalized, such as production of OH by H2O2 plus Fe3+.
摘要
分子氧的连续单电子还原产生超氧自由基（O2-）、过氧化氢（H2O2）、羟基自由基（OH）和水。涉及这些状态的单电子、双电子和四电子偶合在pH 7时的氧化还原电位以电位图的形式呈现。解释了每种电位的意义。完整的电位图使复杂系统合理化，例如H2O2与Fe3+反应生成OH。
