In this contribution, we utilize electronic-structure calculations to unravel complex reaction mechanisms in alkaline environments. We will focus on two technologically-relevant reactions, the oxygen reduction reaction (ORR) on Au(100) and the ammonia oxidation reaction (AOR) on Pt(111). By using solvent-, coverage-, and potential-cognizant static and molecular dynamics simulations in conjunction with microkinetic models, we are going to shed light on the following key questions i. âWhat is the origin of the remarkable activity of Au(100) for ORR in alkaline environment?â[2] and ii. âWhat is source of Pt deactivation in the AOR?â [3-7].
