A New Method for Rapid-Determination of the Potential of Zero Charge for Gold-Vertical-Bar-Solution Interfaces
A new method, based on the response of a thickness shear mode sensor to electrocapillary phenomena, for determination of the potential of zero charge (pzc) at solid metal/solution interfaces is described. The pzc values of gold in the solutions of NaF, Na2SO4, and HClO4 are obtained. The order of the pzc values is as follows : F- > ClO4- > SO42-. This is in good agreement with previous work.
