Establishing a method of reduction of nitroarenes into corresponding amines in water without using flammable sodium borohydride or toxic hydrazine as hydrogen source, is quite challenging. Here, we show for the first time the propensity of sub-nanometric rhodium nanoparticles (< 1 nm) supported on ultra-small magnetic nanoparticles (8–10 nm), as reusable catalyst for the nitroarene reduction in aqueous medium using tetrahydroxydiboron (THDB) as reductant.

亚纳米Rh修饰的磁性纳米粒子可作为水中硝基芳烃还原的可重复使用催化剂

建立一种在不使用易燃的硼氢化钠或有毒的肼作为氢源的情况下，将硝基芳烃还原为水中相应胺的方法具有很大的挑战性。在这里，我们首次展示了超小磁性纳米颗粒（8-10 nm）上负载的亚纳米级铑纳米颗粒（<1 nm）作为使用四羟基二硼（THDB）在水性介质中还原硝基芳烃的可重复使用催化剂的倾向。作为还原剂。
