通过原子层沉积在纳米立方体上生长的铂纳米颗粒呈现出预测的WinterBottom形状的立方体对立方体的外延，这与界面和表面自由能的文献值一致。这种热力学稳定的构型应该能经受住严酷的催化条件，以产生稳定的、高比表面积、表面选择性好的催化剂。
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.
