In addition, the STM tip can also be used as a source of low energy electrons for surface modification. Thus far we have completed a detailed study of surface structure and reactivity of tungsten oxide surfaces. The objective of this study is to identify the key structural features required for oxide catalysis and the processes that are important in determining the types of sites that will be available under reaction conditions. These results will help guide development of new oxide materials with stable catalytic sites. Images Click on any of the pictures for a full-size version and description.
