题目：Metal Organic Frameworks Route to in Situ Insertion of Multiwalled Carbon Nanotubes in Co3O4 Polyhedra as Anode Materials for Lithium-Ion Batteries作者：Gang Huang†‡, Feifei Zhang†‡, Xinchuan Du†‡, Yuling Qin†, Dongming Yin†, and Limin Wang*†§ 简介：Hybridizing nanostructured metal oxides with multiwalled carbon nanotubes (MWCNTs) is highly desirable for the improvement of electrochemical performance of lithium-ion batteries. Here, a facile and scalable strategy to fabricate hierarchical porous MWCNTs/Co3O4 nanocomposites has been reported, with the help of a morphology-maintained annealing treatment of carbon nanotubes inserted metal organic frameworks (MOFs). The designed MWCNTs/Co3O4 integrates the high theoretical capacity of Co3O4 and excellent conductivity as well as strong mechanical/chemical stability of MWCNTs. When tested as anode materials for lithium-ion batteries, the nanocomposite displays a high reversible capacity of 813 mAh g–1 at a current density of 100 mA g–1 after 100 charge–discharge cycles. Even at 1000 mA g–1, a stable capacity as high as 514 mAh g–1 could be maintained. The improved reversible capacity, excellent cycling stability, and good rate capability of MWCNTs/Co3O4 can be attributed to the hierarchical porous structure and the synergistic effect between Co3O4 and MWCNTs. Furthermore, owing to this versatile strategy, binary metal oxides MWCNTs/ZnCo2O4 could also be synthesized as promising anode materials for advanced lithium-ion batteries.其他：ACS Nano, 2015, 9 (2), pp 1592–1599           DOI: 10.1021/nn506252u          Publication Date (Web): January 28, 2015           Copyright © 2015 American Chemical Society 返回小木虫查看更多
