This review analyzes the use of magnetite-based catalysts in various oxidation reactions. It is shown that are most promising candidates from standpoint easy separation reaction zone and reusability. Diverse examples composites discussed, including following reactions: partial methane to formaldehyde; cycloalkanes into alcohols ketones; alkenes with major focus made on benzylic alcohol oxidation; oxidative cracking alkenes; Fenton-type reactions H2O2 as a benign oxidant; removal dyestuff water (including wastewater by oxidation); sulfides thiols; 5-hydroxymethylfurfural platform chemical 2,5-diformylfuran; D-glucose D-gluconic acid; electrocatalytic methanol ethanol. The important best-studied applications magnetic nanoparticles believed be diverse D-glucose, Fenton-like aiming at S- N-compounds ware fuels. Magnetic nanocomposites determined materials meeting range criteria: (1) they should magnetic, (2) contain nanoparticles, (3) consist two (or more) nanocomponents. core–shell used core or decorating discussed review. Three main types can distinguished: systems where phase active considered reaction, for instance, containing metal supported onto nanoparticles; coated one shells (porous non-porous), being not title reaction. exhibit number advantages compared non-magnetic include possibility medium (5–10 times) without significant loss activity, their non-toxicity, low cost, availability, preparation these materials. drawbacks may leaching components; decrease saturation magnetization comparison bulk magnetite; limited accessibility sites due diffusion through shells; complicated composition structure nanomaterials; activity specific surface area; compounds acceptable characteristics. Nevertheless, nanocatalysts stimulate wide liquid-phase reactions, which will Future perspectives considered.
