摘要：

Platinum nanoparticles grown on SrTiO3 nanocuboids via atomic layer deposition exhibit cube-on-cube epitaxy with the predicted Winterbottom shape, consistent with literature values of the interfacial and surface free energies. This thermodyamically stable configuration should survive the rigors of catalytic conditions to create stable, high surface area, face-selective catalysts.
