The precise delivery of chemical and electron equivalents is crucial to nearly every process on earth, and underlie many current and prospective renewable energy technologies. The importance of controlling the delivery of proton and electron equivalents to metal reactive-oxygen species have long been recognized for oxygen reduction, and has contributed to the rational development of catalysts with higher activity and selectivity at lower overpotentials. Introduction of Lewis acidic metal-ions has recently emerged as a powerful way to further alter catalyst rates and selectivities in the chemical and electrochemical reduction of oxygen; however, the exact role of the species in these processes remain limited. In this talk, I will share our group’s recent advances in the chemistry of reactive-oxygen species of group III and the lanthanides (rare-earth metals). This includes the discovery, characterization, and reactivity of novel species and intermediates, as well as the development of new catalytic processes which are highly resistant to parasitic reactions common to traditional design strategies.
