| description | This review focuses on the magnetic properties, structure, synthesis and application as catalysts of magnetic nanoparticles of iron oxides. In recent years there have been many advances in its synthesis, control of size and shape, which highlights methods such as co-precipitation, microemulsion, hydrothermal and solvothermal synthesis, among many others. But because the nanoparticles of iron oxides are easily oxidizable by the environment and by acidic means, it is necessary to coat them or protect them with non-magnetic materials that in many cases also function as functionalizing substances to which the phase is attached active Thus, the range of possibilities for protective substances and compounds, such as inorganic oxides, polymers and metals, is broad, as are the techniques for their functionalization. Magnetic nanoparticles, once functionalized, can be used as building blocks for the manufacture of a wide variety of catalytic systems, and in this work we will briefly review some of these systems and their application in different processes such as Organic Synthesis reactions, photocatalysis and elimination of metals and other substances in wastewater, to name a few examples. Finally, some trends and future perspectives in these research areas will be delineated. |

Esta revisión se centra en las propiedades magnéticas, estructura, síntesis y aplicación como catalizadores de las nanopartículas magnéticas de óxidos de hierro. En los últimos años son muchos los avances logrados respecto a su síntesis, control del tamaño y forma, donde se destacan métodos como la co-precipitación, microemulsión, síntesis hidrotermal y solvotermal, entre muchas otras. Pero debido a que las nanoparticulas de óxidos de hierro son fácilmente oxidables por el medio amiente y por medios ácidos, se ve la necesidad de recubrirlas o protegerlas con materiales no magnéticos que en muchos casos funcionan también como sustancias funcionalizadoras a las cuales se une la fase activa. Así, es amplio el abanico de posibilidades de sustancias y compuestos protectores, tales como óxidos inorgánicos, polímeros y metales, al igual las técnicas para su funcionalización. Las nanopartículas magnéticas una vez funcionalizadas pueden usarse como bloques de construcción para la fabricación de una gran variedad de sistemas catalíticos, y en este trabajo se revisará brevemente algunos de estos sistemas y su aplicación en diferentes procesos como reacciones de Síntesis Orgánica, fotocatálisis y eliminación de metales y otras sustancias en aguas residuales, por citar algunos ejemplos. Finalmente, se delinearán algunas tendencias y perspectivas futuras en estas áreas de investigación.
