In the present review, we summarized the applications of magnetic spinel ferrite nanoparticles as catalysts in organic reactions and transformations. Catalytic applications are comprised of using mostly cobalt, nickel, copper, and zinc ferrites, along with their mixed-metal combinations based on nano ferrites. The spinel ferrites (SFs) are gained principally by wet-chemical, sol-gel or co-precipitation methods, more infrequently by the mechanical high-energy ball milling, spark plasma sintering, sonochemical technique, microwave heating or hydrothermal route. Catalytic processes with the application of ferrite nanoparticles are included decomposition (in particular photocatalytic), reactions of dehydrogenation, oxidation, alkylation, CC coupling, removing organic/inorganic contaminants from aqueous solutions. As significant and remarkable advantages, ferrite nanocatalysts not only are environmentally benign and compatible with green chemistry aspects but also can be simply recovered from reaction systems and recycled up to several times almost without significant loss of their catalytic activity.
在本综述中，我们总结了磁性尖晶石铁氧体纳米颗粒作为催化剂在有机反应和转化中的应用。催化应用主要包括使用钴、镍、铜和锌铁氧体，以及基于纳米铁氧体的混合金属组合。尖晶石铁氧体（SFs）主要通过湿化学法、溶胶 - 凝胶法或共沉淀法获得，较少通过机械高能球磨、放电等离子烧结、声化学技术、微波加热或水热法制备。应用铁氧体纳米颗粒的催化过程包括分解（特别是光催化）、脱氢反应、氧化反应、烷基化反应、碳 - 碳偶联反应、从水溶液中去除有机/无机污染物。作为显著的优势，铁氧体纳米催化剂不仅对环境友好且符合绿色化学要求，还能从反应体系中轻松回收并循环使用数次，几乎不会显著损失其催化活性。
