Structural–chemical transformations of quasi-two-dimensional iron–oxygen nanostructures occurring at transport reduction were studied using NGR spectroscopy. It has been found that isolated iron–oxygen groups [i.e. groups containing iron and oxygen atoms: ≡Si–O–Fe(OH)2 and (≡Si–O–)2–FeOH] forming surface monolayers were not reduced at T = 400–600° C because of their covalent bonding with the silica surface. Reduction of iron oxide microparticles (microstructures) at T ≥ 600°C C resulted in the formation of metal iron in the form of α-Fe. It has been revealed that in the course of transport reduction (TR) of the samples with deposited monolayers (one or four monolayers) at T ≥ 600° C bulk phases of iron silicate and metal iron were formed. It has also been shown that the features of structural–chemical transformations of supported iron–oxygen nanolayers were in relation with the specific character of phase formation within nanoscale structures.
