Nanoporous PdCo Catalyst for Microfuel Cells: Electrodeposition and Dealloying

Figure 2

Phase diagram of PdCo system showing the composition range where oxygen reduction reaction is enhanced. The diagram was based on the figure reported in the literature [43]. Mainly, the phase is an fcc solid solution. In specific composition range, the alloy contains ordered fcc phase (L1₂ type) or ordered face-centered tetragonal phase (L1₀ type).
