Application of magnetic iron oxide nanoparticles in catalysts as catalyst base

When synthesizing magnetic nanoparticles, some key conditions such as inherent magnetic properties, size and shape of nanoparticles, surface coatings and surface charge of nanoparticles, stability in aqueous medium and their non-toxicity should be considered. By choosing a suitable synthesis method, the size, shape, surface coating and colloid stability of the magnetic nanoparticles can be controlled optimally. In the selection of magnetic matter, iron oxides have good magnetic properties compared to other magnetic nanoparticles, and, on the other hand, exhibit high stability against degradation. These nanoparticles also have lower toxicity. To date, various methods have been developed for the synthesis of magnetic nanoparticles. This article will explain some of them
