This paper provides experimental evidences of crystalline rearrangements on platinum surfaces by applying square wave potential perturbations. The phenomenon was followed by differential ex situ X-ray diffraction patterns and in situ cyclic voltammetry in sulfuric acid solutions. Various upper and lower potential limits were employed covering anion, hydrogen, and/or oxygen adsorption ranges. When the -0.05 to 1.50 V (vs. reversible hydrogen) potential region is covered an increase in the distribution of (200) planes is observed. However, when the 0.65 to 1.50 V region is used, (220), (311), and (420) planes developed. The development of a longitudinal propagation mode is responsible for this rearrangement. The new equilibrium position of the platinum surface atoms in the lattice was calculated from the minimization of the potential energy expression.
