Abstract (EN): The minimum in the differential capacity of (111), (100), (110), (210) and (311) single-crystal gold faces in contact with dilute solutions of HClO4 as a function of the temperature was used to estimate the temperature coefficient of the potential of zero charge of these interfaces. The results are discussed in terms of the interaction of water with the metallic surfaces and the role played by the surface atomic arrangement. The strength of Au (hkl)-water interactions are proposed to be in the order Au (111) > Au (311) > Au (100) > Au (110) > Au (210) ¿ Hg. © 1990.
