摘要: Abstract The spontaneous deposition of Pd directly onto Fecralloy foam substrates was investigated as a simple and convenient approach to the preparation structured technological catalysts for environmental applications, avoiding issues typically encountered with washcoated systems. Characterization freshly prepared included ion chromatography ICP–MS, assess loading, cyclic voltammetry, estimate surface area, SEM–EDX, XRD TPR/TPO. Cyclic SEM–EDX were performed also on reaction aged samples. CO CH 4 catalytic oxidation under lean conditions selected test reactions occurring respectively in low (100–300 °C) mid-high (300–600 °C) temperature ranges. Pd–Fecralloy found guarantee good activity an effective utilization noble metal content spite their relatively dispersion.
