The structural features of metal nanoparticles such as crystallite size and shape are important to catalytic activity and selectivity. Thus, correlating the performance of metal nanocatalysts to these structural features is important to understanding and designing better catalysts. The size and shape effects of Pd nanocrystals are examined as they are applied as semihydrogenation catalysts. Seed-mediated growth methods were used to achieve samples composed of different-sized {100}-terminated Pd nanocubes and {111}-terminated Pd nanoctahedra, which served as model systems to evaluate the role of surface structure to activity and selectivity. The size of the nanocrystals was easily tuned by controlling the amount of metal deposited per seed. The selection of capping agent provided a means of manipulating the final shape of the nanocrystals. Finally, the catalysis results from this study will facilitate the decoupling of the size and shape contributions to the geometric parameters of Pd nanocatalysts.
