Colloid deposition was used to prepare catalysts with controlled-size palladium nanoparticles supported on γ-Al2O3. The rate of ethylene hydrogenation was found to increase with increasing diameter of the palladium nanoparticles in the 4-6 nm range. The effective reaction activation energy was found to be independent of the size of the palladium nanoparticles. Thus, this nanodimensional effect may be a consequence of change in the ratio of the areas of the different crystallographic faces of palladium on the catalyst surface.
