Nanoporous Metals Fabricated through Electrochemical Dealloying of Ag-Au-Pt with Systematic Variation of Au:Pt Ratio
Source abstract
Abstract
Novel nanoporous structures from binary and ternary precursors (Ag-Au-Pt with Pt contents of 1, 2 and 3 at% and 77 at% of Ag) were developed in acidic media by electrochemical dealloying. The average size of the ligaments, composition of the dealloyed layer and real surface area of the resulting structure were investigated, as well as the influence of synthesis parameters such as the dealloying temperature, potential and charge density. Scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and Brunauer-Emmett-Teller surface area were used to characterize the nanoporous structure, in addition to electrochemical methods such as cyclic voltammetry.
