摘要: Palladium surfaces that are modified with O atoms in the subsurface broaden NO reduction temperature regime up to 325 K O2-rich NO+H2+O2 compositions. Compared virgin Pd surfaces, 150 % higher deNOx catalytic activity was observed at reaction maximum. Molecular beam instrument and ambient-pressure photoelectron spectroscopy were employed follow kinetic surface changes. These results open a possibility realize cold-start of NOx (deNOx). DeNOx reported literature supported catalysts after simple calcination air compares well our present observations. Surface modification is likely demonstrate high potential for other reactions relatively low temperatures.
