The art of addition and subtraction : By confining the nucleation and growth of Rh atoms only to the corners and edges of Pd cubic seeds, Pd‐Rh core–frame nanocrystals were obtained with concave side faces. The Pd cores were then selectively removed by oxidative etching to generate Rh cubic nanoframes with a highly open structure (see picture).
