Preparation of magnesium diniobate by solid-state reactions and its role for hydrogen storage

A ternary compound of magnesium diniobate (MgNb2O6) was prepared by solid–state reactions in order to understand the role of transition metal oxides as a promoter/catalyst for hydrogen storage in Mg/MgH2 systems. MgNb2O6 was prepared in almost pure form in oxidizing conditions by annealing a stoichi...
