Description
Summary:Metal oxide electronics materials possess splendid application prospect in lithium ions battery. In this work, Fe 2 O 3 @TiO 2 nanospheres are synthesized via a facile chemical co-precipitation method combined with hydrolysis method. Field-emission scanning electron microscopy, transmission electron microscopy reveals that the as-prepared Fe 2 O 3 @TiO 2 is composed of TiO 2 as a rigid nanoshell and Fe 2 O 3 as a core. It is found that the TiO 2 shell is effective for improving the electrical conductivity and structural stability. This novel core–shell structure showed enhanced electrochemical properties is mainly attributed to the inert TiO 2 preventing the Fe 2 O 3 nanoparticles from pulverization and aggregation and the synergistic effects between the Fe 2 O 3 core and TiO 2 shell.
