Platinum-group-metal materials were recovered from fuel cells and studied as catalysts for the total oxidation of propane as model reaction. Therefore a representative number of metal-foam catalysts containing platinum, palladium, and ruthenium in certain ratios were prepared and investigated. Interestingly, particularly active catalysts were observed with a high fraction of one metal and small amounts of the other two metals. This suggests a principal trend for preparing efficient catalysts using ternary-precious-metal systems. For the recycling of fuel-cell compounds the composition of the material could be varied by the substitution or addition of appropriate amounts of precious metals to achieve the highest performance.
