Designed multimetallic Pd nanosponges with enhanced electrocatalytic activity for ethylene glycol and glycerol oxidation

Abstract

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.
