We report an effective synthesis of surfactant-free multimetallic Pd nanosponges with tunable compositions using EDTA as the structure-directing reagent and NaBH4 as the reducing reagent. Among the mono-metallic Pd, binary PdNi and PdAu, ternary PdAuNi nanosponges and commercial Pt/C catalysts studied, Pd62Au21Ni17 nanosponges exhibit excellent activities and are the most efficient nanoparticle catalysts ever reported for both ethylene glycol and glycerol oxidation reactions.
