Surface Characterization of Oxides and Halides

The Use of HRTEM and Scanning Electron Microscopy to Investigate the Morphology of Oxides and Chlorides Comparison of the Surface Definition of Dispersed Materials, Films, and Single Crystals 

For catalytic applications, the oxides and halides described so far are usually prepared as microcrystalline powders, with the dimensions of the microcrystals varying from 10 to 100 nm. To investigate the surface properties of these oxides and correlate them with properties of well-defined surface structures, we have to answer the following questions  

Which types of faces do the microcrystals expose (or, alternatively, what are their morphologies)  

What is the relative fraction of atoms on faces, edges, steps, corners, and other surface defects  

How flat and regular are the faces defining the morphologies of the microcrystals
