X射线反射率测量用于确定Pt（001）/溶液界面的结构作为在碱性和酸性电解质中施加的电势的函数。与Pt（001）/真空界面不同，电解质界面在所有电位下均未重构。第一和第二层之间的晶格间距被发现是一个功能的潜在的区域中，大约一个单层的H被吸附。在碱性电解质中膨胀率可达晶格间距（0.05 A）的2.5%，在酸性电解质中膨胀率可达晶格间距的1
X-ray reflectivity measurements were used to determine the structure of the Pt(001)/solution interface as a function of the applied potential in alkaline and acid electrolytes. Unlike the Pt(001)/vacuum interface, the electrolyte interface was found to be unreconstructed at all potentials. The lattice spacing between the first and second layer was found to be a function of potential in the region where approximately a monolayer of H was adsorbed. The expansion was up to 2.5% of a lattice spacing (0.05 A) in alkaline electrolyte, and up to 1% of a lattice spacing in acid electrolytes
