HER measurements of two samples both before and after the dealloying process. Current densities were calculated with respect to the geometric area of the sample. The initial copper content in the films are (a) 12.6±0.6% and (b) 21.4±1.1%. The copper content in the dealloyed films are (a) 11.4±0.6% and (b) 13.9±0.7%.
