The research proposed is directed at the discovery of superior catalysts for the electrochemical reduction of dioxygen and other technologically important molecules. The proposal will also involve work on the development of new catalysts for reactions that require the transfer of multiple electrons. Finally, a new method for determination of the rates of electron transfer across liquid/liquid interfaces will be used for the study of electron transfers in the absence of accompanying ion transfers. Substituted porphyrins will be used as mediators for the reduction of dioxygen. Heteropolyanions will be used as reservoirs of electrons for multiple electron transfer reactions. Applications to improved fuel cells and air batteries are envisioned.

所提出的研究旨在发现用于电化学还原分子氧和其他技术上重要的分子的上级催化剂。 该提案还将涉及为需要多电子转移的反应开发新催化剂的工作。 最后，一种确定液/液界面电子转移速率的新方法将用于研究在没有伴随离子转移的情况下的电子转移。 取代的卟啉将被用作介体用于还原分子氧。 杂多阴离子将被用作多电子转移反应的电子库。 设想应用于改进的燃料电池和空气电池。
