Advanced Energy Materials, EarlyView.Pt/C catalysts differing only in the locality of the Pt nanoparticles, whether inside or outside of the pores of the same carbon support, are needed to study the effect of said locality. Depending on the carbon support used, nanoparticles inside the pores can show hindered accessibility and ORR performance.

Advanced Energy Materials, EarlyView.Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...
