对于许多重要反应来说，赋予高活性催化剂以动量传递效率将是非常有趣的。然而，由于催化剂与搅拌装置之间的相互作用，铁磁催化剂的本征磁性难以开发。本文合成了一种具有催化活性的超顺磁性co -碳- rgo复合材料（CCGC），并将其用作纳米致动器，同时实现NaBH4或H3NBH3的动量传递和水解，用于制氢。CCGC在间歇式或连续流反应器中磁传递动量。外加磁场驱动催化剂传递动量，实现优异的搅拌效果。催化剂可以固定在连续流中的指定位置，以实现高效分离。催化剂与反应混合物的分离也变得容易。CCGC作为污染物吸附剂，在没有磁力或机械搅拌的情况下，对水中罗丹明B （Rh-B）的去除效果良好。其独特的动量传递特性以及优异的催化和吸附性能，保证了其在相应领域的应用前景。
It will be very interesting for many important reactions to endow highly active catalysts with momentum-transfer efficiency. However, the intrinsic magnetism of ferromagnetic catalysts is difficult to exploit due to the interaction between the catalyst and stirring devices. Herein, a catalytically active and super paramagnetic Co–carbon–rGO composite (CCGC) was synthesized and used as a nanoactuator to simultaneously achieve momentum-transfer and hydrolysis of NaBH4 or H3NBH3 for hydrogen production. The CCGC magnetically transferred momentum in a batch or continuous flow reactor. The external magnetic field can drive the catalyst to transfer momentum for excellent agitation. The catalyst can be fixed at an appointed position in the continuous flow for efficient separation. The separation of the catalyst from the reaction mixture also becomes facile. The CCGC showed superior retention as a pollutant adsorbent for the removal of Rhodamine B (Rh-B) from water in the absence of magnetic or mechanical stirring apparatus. The unique momentum-transfer properties, as well as excellent catalysis and adsorption, warrant its promising application in the corresponding fields.
