摘要: While the synthesis of TiO2 hollow structures is well-established, in most cases it particularly difficult to control crystallization solution or by calcination. As a result, do not really exhibit enhanced lithium storage properties. Herein, we report simple and cost-effective template-assisted method synthesize anatase spheres composed highly crystalline nanocrystals, which carbonaceous (C) spheres are chosen as removable template. The release gaseous species from combustion C spheres may inhibit growth crystallites so that instead small nanocrystals generated. size high crystallinity primary nanoparticles structural integrity gives rise significant improvements cycling stability rate performance spheres.
