阶梯式铂表面氢化后会变得疏水。尽管Pt（533）和Pt（553）表面具有相似的几何形状，但在氘化表面上的疏水性却惊人地不同：在Pt（533）上，表面是疏水的，水在台阶上聚集，而在Pt（553）上，整个表面是湿的。
Stepped platinum surfaces can become hydrophobic when they are hydrogenated. Even though the Pt(533) and Pt(553) surfaces have similar geometries, the hydrophobicity on the deuterated surface is surprisingly different: on Pt(533) the surface is hydrophobic with water clustering at steps, whereas the entire surface is wet on Pt(553).
