Cyclic voltammetry in 0.1 M H2SO4 using Pd/C electrocatalysts with distinct metal-to-carbon ratio, Pd black and a Pd wire electrodes reveals unambiguously metal loading effects, such as a decrease in the peak potential for the reduction of palladium oxide (PdO), an increase of the charges of desorption of hydrogen, and formation/reduction of PdO with the Pd content. Such effects need to be taken into account when designing Pd-based Fuel Cells electrocatalysts.17748-17752engCarbonCyclic voltammetryElectrocatalystsMetal loadingPalladiumArtigo10.1016/j.ijhydene.2018.07.137Acesso aberto2-s2.0-850515222902-s2.0-85051522290.pdf87991910784514670000-0001-7897-1905
