Synthesis of Nanowire and Mesoporous Low-Temperature LiCoO_2 by a Post-Templating Reaction

摘要

The synthesis of transition-metal oxides with controlled nanostructures,such as mesoporous solids,nanotubes,or nanowires,is an important task because such nanostructuring may have a profound influence on the properties of these materials.This includes nanostructured materials for energy conversion and storage.Soft templating routes have been used to synthesize mesoporous transition-metal compounds,for example,Nb_2O_5,TiO_2,MnO_x.,and Fe_2O_3;however,the materials often have poorly crystallized walls and are thermally unstable,which limits their applications.
