This minireview summarizes the most important synthetic methodologies for obtaining 2-D FeII SCO particles in nanometric scale and their magnetic behavior.
A series of nanometric isoreticular and/or functionalized analogues of the mesoporous environmentally-friendly iron(III) polycarboxylates MIL-100/101 have been successfully synthesized. Their exceptional pore size, of up to 68 Å, together with their relatively good stability in solvents, makes them promising candidates for heterogeneous catalysis or inclusion of large molecules, among others.
Preparation of magnetitelmaghemite nanometric particles is reported from the precipitation of ferrous dodecyl sulfate micellar solution with methylamine. The size of nanocrystals is controlled by the micellar concentration and by temperature. It varies from 3.3nm to llnm. Magnetic properties are studied for various sizes of maghemite particles.
