Size and shape do matter sometimes : Nanocrystals of noble metals are attractive for use as catalysts because of their high surface‐to‐volume ratios and high surface energies, which result in their surface atoms being highly active. Recently reported platinum nanocrystals with a novel tetrahexahedral shape reveal an enhanced catalytic activity over their “amorphous” nanoparticle counterparts.
