We systematically investigated the shape transformation of Pt nanocrystals between high-index facets and low-index facets by an electrochemical method, and revealed the change processes and rules of nanocrystal shapes and surface structure. The coordination number of surface atoms can be continuously tuned from 6 to 9 by controlling the regrowth/etching rate.
