Top-down tailoring of nanostructured manganese molybdate enhances its lithium storage properties

摘要: Binary transition metal oxide manganese molybdate is progressively tailored by a facile top-down strategy using dopamine as scissors. Aggregated micron-whisker structures are successfully converted to nanospheres in the aqueous phase at room temperature, whose morphology evolution witnessed direct observation of scanning electron microscopy. Meanwhile, nitrogen-doped carbon introduced composite after and controllable annealing treatment. Benefiting from structure tailoring surface modification, formed molybdate/nitrogen-doped composites exhibit highly reversible capacity excellent long-term cycling stability when evaluated anodes for lithium ion batteries. It believed that this synchronously regulating properties will inspire variation structural design other molybdate/carbon composites.
