摘要：

In this work, we report an interesting synthesis of unusual rutile TiO2 nanosheets with exposed high-energy (001) facets, which form hierarchical microspheres that closely resemble the natural "desert rose". These high-energy (001) surfaces are stabilized by amorphous molybdenum trioxide (MoO3), which is homogeneously dispersed on the TiO2 nanosheets. The as-prepared unique TiO2-MoO3 hybrid structure exhibits improved lithium storage capabilities.
