Dehydrogenation of cyclohexane was performed on subnanometer and few nanometer size platinum- and cobalt-based catalysts. The activity and selectivity was dependent of  the composition and functionalization of the support material, the size and doping of the nanocatalyst. DFT calculations provided important insight into the structure, stability and energetics of clusters.
