Abstract—
X-ray diffraction and scanning electron microscopy data demonstrate that the thermal stability limit of thin PdO films in an oxygen atmosphere rises from 1083 ± 5 to 1133 ± 5 K as the thickness of the starting Pd layers increases from ~10 to ~95 nm, respectively. Unlike the continuous starting metallic palladium layers, the Pd nanostructures resulting from complete thermal decomposition of thin PdO films consist of isolated hemispheric nanocrystallites having well-defined faceting. According to the X-ray diffraction results, the Pd crystallites have (111) and (100) preferential alignment.
