Abstract

Abstract text (incl. figure legends and references)

Methanol Steam Reforming (MSR) is an important reaction converting methanol into hydrogen (CH3OH + H2O à 3 H2 + CO2) holding promise for easy fuel handling in hydrogen based applications like fuel cells. ZnPd/ZnO nanoparticles are promising MSR catalysts due to their high CO2 selectivity, stability and activity.1 It is known that their properties depend strongly on their microstructure and particle size, thus, also on their preparation method.2-5 In order to understand their microstructural evolution during preparation, the calcination of supported Pd(NO3)2 in O2 was studied using in situ high resolution scanning transmission electron microscopy. For additional pre- and post characterisation energy dispersive x-ray spectroscopy and electron energy loss spectroscopy were applied.
