MOF‐derived Co₃S₄/CN hollow nanoboxes (CN=nitrogen‐doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H₂ as the reducing agent. The catalyst provides high conversion efficiencies and selectivities for a variety of nitroarene substrates that contain electron‐donating or electron‐withdrawing substituents under mild reaction conditions (in methanol at 60 °C). Further, the nanobox inhibits both dehalogenation and vinyl hydrogenation reactions, which are common limitations of state‐of‐the‐art Pd‐based catalysts. Because the reactions result in pure aniline products, the need for separation by column chromatography is eliminated. The resulting anilines are easily separated from the methanolic reaction solution in just three simple steps (centrifugation, decantation, and drying). If employed in industrial processes, catalysts of this kind would significantly reduce the amount of waste organic solvent generated and thus satisfy the need for sustainable chemical processes.

金属-有机框架衍生的Co3S4空心纳米盒，用于选择性还原硝基芳烃

MOF衍生的Co ₃ S ₄ / CN中空纳米盒（CN =氮杂碳）用于在温和的反应条件下与H ₂催化将硝基芳烃化学选择性还原为苯胺作为还原剂。在温和的反应条件下（在60°C的甲醇中），该催化剂可为多种含有给电子或吸电子取代基的硝基芳烃底物提供高转化效率和选择性。此外，纳米盒同时抑制脱卤和乙烯基氢化反应，这是最新的钯基催化剂的常见局限性。因为该反应产生纯的苯胺产物，所以消除了通过柱色谱法分离的需要。只需三个简单的步骤（离心，倾析和干燥）就可以轻松地从甲醇反应溶液中分离出生成的苯胺。如果用于工业过程，
