Controlled Synthesis of Hollow Co–Mo Mixed Oxide Nanostructures and Their Electrocatalytic and Lithium Storage Properties

摘要: Hollow mixed metal oxides have received much attention owing to their great performance for wide potential applications. Here, we successfully prepared hollow Co–Mo oxide nanostructures with controlled structure and compositions, including Co3O4/CoMoO4 heterostructures ball-in-ball CoMoO4 nanospheres. Uniform CoMo-hybrid precursors are through one-pot solvothermal method then transformed into structures after thermal treatment. Importantly, this strategy can be used prepare other ternary Mo-based oxides. In view of the unique heterostructure structure, exhibit better electrocatalytic activity oxygen evolution reaction than CoMoO4. Moreover, as-synthesized carbon-coated nanospheres show excellent lithium storage properties. Our result described here provides a fabricate complicated structure.
