Substoichiometric mixed molybdenum–tungsten oxide nanostructures (MMTONs) with diverse phases and morphologies were prepared using a solvothermal method to investigate the impact of these structural features. With an increase in the Mo content of mixed Mo and W source materials, mixed phases of W 18 O 49 and MoO 2 appear, and the morphology changes from crystalline nanourchins to amorphous nanospheres. Crystalline molybdenum oxides are formed only in the presence of a tungsten precursor that serves as the framework for the creation of the crystalline molybdenum phase.
