O2还原各种催化剂的建议机制进行了讨论，考虑到超氧自由基，过氧化氢和吸附的分子氧的可能作用。特别注意的是集中在O2还原碳和石墨（有和没有表面改性），反常的温度依赖性的塔菲尔斜率O2还原铂，过渡金属大环和热处理的大环。后者提供了相当大的承诺，作为O2还原催化剂结合高活性和良好的稳定性。
The proposed mechanisms for O2reduction on various catalysts are discussed, taking into account the possible role of superoxide radicals, hydogen peroxide and adsorbed dioxygen. Particular attention is focused on O2reduction on carbon and graphite (both with and without surface modifications), the anomalous temperature dependence of the Tafel slope for O2reduction on Pt, transition metal macrocycles and heat treated macrocycles. The latter offer considerable promise as O2reduction catalysts combining high activity with good stability.
