摘要: Abstract The experiments show that the kinetics of O 2 reduction on Pt (with NAFION as electrolyte) is first order in a wide range reaction conditions. Recent DFT calculations indicate during this atomic-oxygen coverage may be appreciable. To adjust these two findings, we analyze corresponding to dissociative and associative mechanisms with participation atomic oxygen. If steps are described by using Langmuir equations, predicted only situations when low. With O–O lateral interactions, model based mechanism able predict first-order pressure even if
