Incorporation of cobalt nanoparticles (Co NPs) in porous iron oxide nanospheres (Fe₃O₄ NSs) templated, glucose derived hollow carbon capsules (HCCs), with an objective to achieve activity and stability simultaneously, facilitates higher catalytic activity of Co NPs in transfer hydrogenation of ketones and aldehydes. A variety of ketones and aldehydes are hydrogenated successfully with excellent yields and high turnover number (TON). This system constitutes one of the most general, heterogeneous, highly stable catalyst, which does not require additives for activation and employs mild reaction conditions. Other significant advantages are low Co content (0.38 mol%) for a catalytic hydrogenation reaction, functional-group tolerance, inexpensive, environmentally benign nature and reusability.

将钴纳米颗粒（Co NPs）掺入多孔氧化铁纳米球（Fe ₃ O ₄（NSs）模板化的，葡萄糖衍生的中空碳胶囊（HCC），目的是同时实现活性和稳定性，有助于Co NPs在酮和醛的转移氢化中具有更高的催化活性。各种酮类和醛类均以成功的高收率和高周转率（TON）成功地进行了氢化。该体系构成了最通用的，非均相的，高度稳定的催化剂之一，该催化剂不需要用于活化的添加剂，并且采用了温和的反应条件。其他显着的优点是用于催化氢化反应的Co含量低（0.38 mol％），对官能团的耐受性，价格便宜，对环境无害的性质和可重复使用性。
