Kinetic control of surface defects is achieved, and cubic, concave cubic, and defect‐rich cubic intermetallic Pt 3 Sn nanocrystals are prepared for the electro‐oxidation of formic acid. The generality of this kinetic approach is demonstrated by the fabrication of Pt–Mn nanocrystals with different surface defects. The defect‐rich nanocrystals exhibit high catalytic activity and stability concurrently, indicating their potential application in fuel cells.
