Anisotropic phase segregation and migration of Pt in nanocrystals en route to nanoframe catalysts

Scientific Achievement

Control of nanoscopic segregation of the elements in Pt-Ni rhombic dodecahedra (RD) was discovered to create a 3-D Pt3Ni nanoframe.

Significance and Impact

Being able to control the element spatial distribution within nanocrystals is an advanced strategy for obtaining catalysts with new morphologies and structure.
