Here we report on a unique nanohybrid made of a molybdenum oxysulfide (MoOxSy) layer on porous TiO2 nanospheres, which has been fabricated in large quantities through a facile photochemical-assembly process. The as-formed core-sheath TiO 2@MoOxSy nanocomposite not only inherits the features of the interior TiO2 nanospheres with high porosity and high surface area, but also possesses enhanced conductivity from the external MoOxSy layer. When evaluated as an anode material for lithium ion batteries, such a unique TiO2@MoOxS y nanohybrid exhibits superior lithium storage performances with high specific capacity and excellent rate capability. The synergetic effects of the enhanced electrical conductivity of uniform MoOxSy coating and the porously nanoarchitectured TiO2 nanocrystal assemblies may endow the TiO2@MoOxSy electrode with remarkable lithium-storage performances.
