Abstract

We report the facile synthesis of a highly efficient, reusable catalyst comprising Cu(II) nanoclusters supported on CuCr2O4 spinel nanoparticles for the oxyamination of benzene to aniline (H2O2 + NH3) under mild aqueous reaction conditions. The synergy between the Cu(II) nanoclusters and CuCr2O4 spinel nanoparticles plays the most vital role towards its high catalytic activity.

摘要

我们报道了一种简便的合成方法，可制备一种高效、可重复使用的催化剂，该催化剂由负载在CuCr₂O₄尖晶石纳米颗粒上的Cu(II)纳米团簇组成，用于在温和的水相反应条件下将苯氧胺化为苯胺（H₂O₂ + NH₃）。Cu(II)纳米团簇与CuCr₂O₄尖晶石纳米颗粒之间的协同作用对其高催化活性起着至关重要的作用。
