oleylamine as both solvent and reductant was very effective for the preparation of the monodispersed nanoalloy. We evaluated the catalytic activity of these AuPd@C nanoalloys for oxidative dehydrogenative coupling of aniline, which showed better catalytic activity than equal amounts of sole Au@C or Pd@C catalyst. The Au1Pd3@C catalyst exhibited the best performance, indicating that the conversion and selectivity
通过共还原法成功制备了一系列具有可调组成的AuPd @ C纳米合

硼烷-
叔丁胺配合物作为还原剂,
油胺作为溶剂和还原剂,对于制备单分散纳米合
金非常有效。我们评估了这些AuPd @ C纳米合
金对
苯胺的氧化脱氢偶联的催化活性,与等量的单独Au @ C或Pd @ C催化剂相比,它们显示出更好的催化活性。Au 1 Pd 3 @C催化剂表现出最好的性能,表明随着Pd组成的增加,转化率和选择性得到改善。但是,如果AuPd合
金中的Pd成分太高,则Au 1 Pd 7在该反应中@C仅获得81%的转化率。
