“…Traditional preparation methods for Pt-based alloys have been focusing on microemulsions [18,19], microwave irradiation [20], electrodeposition [21] and chemical reduction [3,22]. These processes are limited to the tunability of alloy composition, cockamamie, and not suitable for batch production, which hampers the commercialization of DMFCs.…”

“…The mean diameter of the nanoparticles is also shown in Table 1. The narrow size distribution obtained could be attributed to the sodium borohydride method of preparation [54]. Figure 3 shows the cyclic voltammetry of PtAu/C, Au/C and Pt/C electrocatalysts measured in 2.0 mol L -1 NaOH solution normalized by gram of metal.…”

“…The addition of other metals (as an alloy [8][9][10][11][12][13] or by irreversible adsorption [14,15]) to Pt has become the way of tailoring the properties of this metal in order to improve their resistance to the poison formation or its capability for breaking the C-C bonds. The higher performance of bimetallic catalysts toward ethanol oxidation has been attributed to a bifunctional mechanism and to the change of the electronic properties of Pt [16].…”
