Abstract

Nanoboxes with a porous MnO core and amorphous TiO₂shell have been synthesizedviaa wet-chemistry method for the first time. The uniqueness of this material is the core-shell nanostructure composed of a crystalline porous core of MnO and amorphous shell of TiO₂. Reduced graphene oxide (RGO) supported MnO-TiO₂core-shell nanocubes with different Ti : Mn molar ratios demonstrated excellent performance as high-capacity cathode materials for lithium-sulfur (Li-S) batteries. These porous core-shell nanocomposite structures with trapped S crystals also offer a good model to investigate the morphological and structural effects of nanocomposites and their influence on the capacity and stability of Li-S batteries.
