Abstract

The d-band model has been useful in understanding how adsorbate molecules form bonds and interact with a transition metal catalyst surface. Recent research has shown that it is possible to apply the model to nanocluster catalysts on a support structure, but the d-band model has not yet been tested for sub-nanometer clusters. For this research, four atom transition metal clusters are used as catalysts to study bond formation in the dehydrogenation reaction of propane (C­3H8) to propene (C­3H6). Testing whether the d-band model applies for these clusters is a step toward developing possible descriptors of their catalytic activity. Our ultimate goal is to computationally screen bimetallic alloy clusters of varying compositions to determine which are favorable for propane dehydrogenation.
