Reactions of Thorium Oxide Clusters with Water: The Effects of Oxygen Content.

Thorium oxide has many important applications in industry. In this article, theoretical calculations have been carried out to explore the hydrolysis reactions of the ThO (n=1-3) clusters. The reaction mechanisms of the O-deficient ThO and the O-rich ThO are compared with the stoichiometric ThO .

Mononuclear thorium halide clusters ThX (X = F, Cl): gas-phase hydrolysis reactions.

Density functional theory (DFT) calculations have been performed to explore the gas-phase hydrolysis reaction of mononuclear thorium halide clusters ThX4 (X = F, Cl). We have found that the hydrolysis of ThCl4 is easier than that of ThF4. Furthermore, their hydrolysis reactions favor pathways of direct dehydration of Th(OH)4 instead of further hydrolysis of ThOX2.
