“…The formation of a ternary alloy is mainly observed in the Pt-Ru-Ni system [62]. The MOR activity of Pt-Ru-M catalysts was compared in some works [63][64][65][66]. In all these papers Pt-Ru-Ni was reported as the best catalyst for the MOR.…”

“…Fe, Co and Ni were selected as a third metals because the low cost of their precursors, and their effect on PtRu activity for methanol electrooxidation was investigated. [63,64]. Huang et al [63] observed that the addition of M to Pt-Ru enhances the electrocatalytic properties for methanol oxidation and Pt-Ru-Ni has the best catalytic activity and stability.…”

“…Huang et al [63] observed that the addition of M to Pt-Ru enhances the electrocatalytic properties for methanol oxidation and Pt-Ru-Ni has the best catalytic activity and stability. Jeon et al [64] found that, among Pt 45 Ru 45 M 10 /C (M = Fe, Co, and Ni) catalysts, the Pt 45 Ru 45 Fe 10 /C and Pt 45 Ru 45 Ni 10 /C catalysts showed the highest mass activity. Regarding the specific activity, the Pt 45 Ru 45 Ni 10 /C catalysts showed the highest activity, 170% higher than that of a commercial Pt-Ru/C catalyst.…”

“…The dependence of the Pt-Ru-Ni to Pt-Ru MOR specific activity (SA Pt-Ru-Ni /SA Pt-Ru ) electrochemically active surface area (ECSA P-tRu-Ni /ECSA Pt-Rut ), particle size (d Pt-Ru-Ni /d Pt-Ru ) and MOR mass activity (MA Pt-Ru-Ni /MA P-Rut ) ratios in acid media on the Ni/(Ru + Ni) atomic ratio by different datasets [20,26,[63][64][65]70,71] is shown in Figure 6a-d. The SA Pt-Ru-Ni /SA Pt-Ru vs. Ni/(Ru + Ni) plot presents a sharp peak centered at ca.…”

Abstract:In view of a possible use as anode materials in acidic direct alcohol fuel cells, the electro-catalytic activity of Pt-Ni and Pt-M-Ni (M = Ru, Sn) catalysts for methanol and ethanol oxidation has been widely investigated. An overview of literature data regarding the effect of the addition of Ni to Pt and Pt-M on the methanol and ethanol oxidation activity in acid environment of the resulting binary and ternary Ni-containing Pt-based catalysts is presented, highlighting the effect of alloyed and non-alloyed nickel on the catalytic activity of these materials.
