    • The compositions of both octahedral and cubic samples were evaluated using ICP-MS, EDS-SEM, and EDS-TEM methods. For nanoctahedra, the average molar ratio of Pt:Ni was determined as 67:33, 70:30, and 76:24 from three methods, respectively. For nanocubes, it was 71:29, 75:25, and 77:23 (Figure S7 in Supporting Information). Content of W was determined as zero from both samples using any of the above methods.

    • To minimize the measurement error, the diagonal of each projected image was measured and its equivalent side length was subsequently calculated based on the assumption that the projection image of each nanocrystal is exactly square.
