摘要：

In this work, the catalytic activity is correlated to the structures of the tungsten oxides surfaces and bulks deduced from XPS, XAS (XANES) and XRD data. The reactivity of 2-methyl-pentane was tested on WO3 and WO2 powders activated under H-2 at various temperatures. When palladium is added to these systems the step of hydrogenation-dehydrogenation is highly favoured which results in a much better activity of the catalysts in isomerization providing no formation of metallic tungsten is occured.
