Cubic, octahedral and rhombic dodecahedral Pd nanocrystals were synthesized and examined as nanocatalysts for electro-oxidation of ethanol and ethylene glycol. Combined electrochemical measurements and density functional theory calculations reveal that nanofacet-dependent affinity and reactivity of OH and CO are closely linked to the C2 alcohol oxidation activities, with the highest reactivity found on the Pd nanocubes bounded by {100} facets.
合成了立方、八面体和菱形十二面体的钯纳米晶体，并将其作为乙醇和乙二醇电氧化的纳米催化剂进行了研究。电化学测量和密度泛函理论计算相结合的结果表明，OH和CO的纳米面依赖性亲和力和反应活性与C2醇氧化活性密切相关，在由{100}面界定的钯纳米立方体上发现了最高的反应活性。
