Abstract


We present an electrochemical study of AuCu (0 0 1) single crystal surfaces in 0.1 mol dm HSO and 0.1 mol dm HSO + 0.1 mmol dm HCl, and of CuAu (0 0 1) in 0.1 mol dm HSO . The focus is on in situ scanning tunneling microscopy experiments. The changes of the surface morphology, which are time- and potential-dependent, have been observed, clearly resolving single atomic steps and mono-atomic islands and pits. Chloride additives enhance the surface diffusion and respective morphologies are observed earlier. All surfaces have shown considerable roughening already in the passive region far below the critical potential. © 2010 Elsevier Ltd All rights reserved.
