摘要：

Potentials of zero charge, E(sigma=0), and the temperature coefficients of E(sigma=0) for stepped surfaces of sold single crystals (511), (533), (331) and (311) were obtained from the minimum of the differential capacity curve in dilute HClO4 solutions. The results are compared with those obtained for the low index faces and dilute in terms of the effect of the surface density of steps and the step orientation. The possible relevance of the effect of steps on the interaction of water with gold surfaces is discussed.
