Abstract
An increase in the limiting oxidation number of V2+ions in the presence of nitrogen in the Mg(OH)2–V(OH)2system was found. This phenomenon was interpreted from the standpoint of the existence of a critical size of vanadium clusters in an ion layer of the mixed hydroxide. The attainment of this critical size is necessary for the reduction of N2and the release of H2. This hypothesis also explains the specific activity of the system as an extremal function of the concentration of vanadium(II) at a constant Mg : V ratio. The effect of solvent (methanol–water) composition on the rate of nitrogen reduction supports the idea that the concentration of free water in the system plays a decisive role in this process. An increase in the intensity of H/D exchange in the presence of nitrogen, which is similar to that observed in biological systems, was found.
