Shishkin, M. Sokol, A. Vostrikov] It was found that bulk samples of molybdenum 〈Mo〉 are oxidized by supercritical water forming nanoparticles of monocline MoO2. The average size of nanoparticles obtained at uniform heating of 〈Mo〉 with supercritical water was about 27 nm, and the size of agglomerates of nanoparticles was ≤ 1 μm. From time dependence of the amount of formed H2 n H2(t), we have determined kinetic parameters of 〈Mo〉 transition to MoO2 particles. The dependence dn H2/dt is characterized by the presence of two pronounced maxima. This is explained by the change of mutual diffusion of H2 and H2O molecules along with the growth of thickness of the layer of MoO2 nanoparticles.
