Investigation of stabilization of α-Fe particles in pores of silica SBA-15 in a hexane atmosphere

The present paper is devoted to the investigation of the possibility to stabilize the metallic state of iron nanoparticles (10–14 nm) in pores of a mesoporous silica SBA-15, using adsorption of n-hexane from a gas phase at room temperature. By means of the method of Moessbauer spectroscopy and measurements of ferromagnetic properties (measurements of magnetization), it is shown that the sample treated with n-hexane in the gas phase preserves its chemical composition and ferromagnetic properties after a month of storage in air.
