【 摘 要 】

The focus of this project was catalysis by ???proton coupled electron transfer??? (PCET) to metal bound fragments derived from the most abundant small molecules (i. e. O₂ and N₂). There are many important chemical challenges that are tied to this fundamental reaction type. Among these are: metal catalyzed oxidations of organic molecules utilizing O₂ as the oxidant; reduction of O₂ to water close to the thermodynamic potential ??? in other words, the cathode of any fuel cell based on reactions with O ₂; transfer of reduced nitrogen species to organic substrates; fixation of nitrogen at modest temperatures and pressures. Any one of these problems has obvious implications for the generation and/or utilization of energy on a large scale.
