Scanning electron microscopy metal oxide deposition

The research involves the development of techniques for deposition of porous catalyst layers by defining the conditions of pressure, sputter rates, and target configurations that will result in appropriate compositions and morphology for the catalyst layer. The effect of catalyst structure and composition on the activity of the catalyst layers will be characterized by x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), x-ray absorption spectroscopy (XAS), and electrochemical polarization studies in half cells and full cells. New base metal and noble metal alloys and oxides will also be studied with an aim to identify new compositions that will result in enhanced activity. The catalyst activity target is 2500 mW/mg of anode catalyst. 

In any event. Mg deposition on bare metallic surfaces (oxide-film and passivation free) is not at all dendritic and is highly reversible. Figure 13.11 shows the typical Mg deposition morphology scanning electron microscopy, (SEM, images) in two types of Mg-Al-Cl-R complex solutions in THF. Mg...
