conditions (e.g. 70 °C, 20 bar H2). The advantage of this novel catalytic material is showcased for industrially important substrates, including adipodinitrile, picolinonitrile, and fatty acid nitriles. Notably, the developed system outperformed all other tested commercial catalysts, for example, Raney Nickel and even noble‐metal‐based systems in these transformations.
制备了由金属氧化物和几丁质衍生的碳组成的钴掺杂杂化材料,对其进行了表征并进行了工业相关腈加氢测试。在700°C下热解后,负载在MgO上的最佳催化剂显示了用碳包裹的Co纳米颗粒修饰的氧化镁纳米立方体。这种特殊的结构允许在温和的条件下(例如70°C,20 bar H 2)将各种苛刻的腈选择性氢化为相应的伯胺。)。这种新型催化材料的优势在工业上重要的底物上得到了展示,这些底物包括己二腈,吡咯腈和脂肪酸腈。值得注意的是,在这些转换中,开发的系统优于所有其他经过测试的商业催化剂,例如阮内镍,甚至贵金属基系统。
