The hercynite cycle is one of the most efficient means of generating hydrogen, which is achieved by repetition of a cycle of two steps, oxidation and reduction steps. To investigate the microscopic mechanism of the oxidation processes in the hercynite cycle, we performed first-principles molecular dynamics simulations for the reaction of a Fe₂Co(Al₂O₄)₃ cluster with water molecules. In this simulations, the adsorption and dissociation reactions of water molecules are observed on the cluster surface. The active sites of these reactions are investigated.
