摘要：

This way ORR that: Theoretical investigations on the oxygen reduction reaction (ORR) mechanism using first-principles quantum chemistry are presented. Explicit analysis of potential-dependent mechanisms shows how subtle changes in conditions alter ORR reaction processes. Importantly, a kinetics-based model reproduces experimental observations for products and quantitative potential ranges. Copyright © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
