Here, we report that various monodispersed metal nanoparticles (Ag, Pt, Co, Cu, Ni, Pd, and Au) efficiently activated molecular oxygen under mild conditions, illustrated by the aerobic oxidation of anilines to form either symmetric or asymmetric aromatic azo compounds. This discovery indicates that exploiting the catalytic power of nanoparticles could enable sustainable chemistry suitable for important
开发在温和条件下用于活化氧的有效催化剂是极富挑战性的,但是可取的。在这里,我们报道了各种单分散的
金属纳米粒子(Ag,Pt,Co,Cu,Ni,Pd和Au)在温和的条件下有效地活化了分子氧,这可以通过
苯胺的有氧氧化来形成对称或不对称的芳族偶氮化合物来说明。这一发现表明,利用纳米颗粒的催化能力可以实现适用于重要氧化反应的可持续
