Abstract

Kinetic energy barriers that have entirely different origins are the reasons for the impedance of the catalytic N₂O/CO redox cycle mediated by both [YAlO₂]^+. and [Y₂O ₂]^+. clusters (see scheme). While oxidation with N ₂O is the bottleneck for [YAlO₂]^+., oxidation of [Y₂O₂]^+. with N₂O is possible, but reduction of [Y₂O₃]^+. by CO is prevented. This arises because of "doping" effects which can control local charges and spin distributions.
