The particle size was tailored by the sur-factant: precursor molar ratio ([Surf.]:[Prec.])according to there-ference [15]. The preparation was magnetically stirred and heated up to the boiling temperature T535 K for 120 min. After synthesis the nanoparticles were extracted by adding ethanol followed by centrifugation(14,000rpm/30min). After that,they were washed with acetone and centrifuged once again. The final sample consists in a black powder constituted by cobalt ferrite nanoparticles covered with an oleic acid layer, which is strongly linked to the surface, improving the chemical stability, and avoiding agglomeration. The samples were labeled S2,S5,and S7 with mean diameter 2.0,4.5,and 7.0 nm respectively, obtained from the TEM analysis., 14024-18-1

Nanosized Fe2O3 was synthesized by the thermolysisof an iron-containing precursor in a dispersion medium. Iron acetylacetonate prepared as describedin [7] was used as a precursor; the dispersion medium was diphenyl ether (DPE). The choice of DPE wasbased on the thermal stability, high boiling point (259C), and low toxicity of this material. Iron acetylacetonate(0.5 g) was dissolved in 10 mL of DPE;40 mL of DPE in a two-necked round-bottom flaske quipped with a reflux condenser was heated in an oil bath to 200C under vigorous stirring with a magnetic stirrer. After that, using a syringe, the iron acetylacetonate solution was rapidly introduced into hot DPE. The resulting mixture was held under vigorous stirring for 2 h to provide the completion of thermolysis and the formation of iron oxide particles; after that, the mixture was cooled and analyzed. To study the features of reduction of Fe2O3 and the chemisorption processes involving it, DPE was removed by vacuum distillation; the resulting material was a black powder.
