Аннотация
We have elucidated the mechanism of CO oxidation catalyzed by AlPdn (n = 1–3) clusters through first-principle density-functional theory (DFT) calculation. It is found that these subnanometer species transfer into reaction complexes which catalyzes CO oxidation through two different mechanisms, occurring via Langmuir-Hinshelwood paths. It is shown that mixing two different metals (Al and Pd) can have more beneficial effects than pure palladium on the catalytic activity and the alloyed AlPd2 cluster is proposed as the best effective nanocatalysts.
