近日，实验室李欣同学、陈梁老师，成功制备了锚定在2DN掺杂碳纳米片（Co3O2 NDs/NCN）杂化物上的Co3O2纳米点，作LIB的阳极时表现出优异的储锂性能的论文发表在Journal Of Alloys And Compounds。
The design and exploitation of advanced transition metal oxides (TMO)/carbon hybrid anodes remain significant but challenging for the evolution of lithium-ion batteries (LIBs). In this work, Co3O4 nanodots anchored into 2D N-doped carbon nanosheets (Co3O4 NDs/NCN) hybrid is successfully fabricated by a facile salt-template assisted pyrolysis strategy using glucose, Co(NO3)2 center dot 6H2O and NaCl salt template as reaction precursors. The morphology, structure and composition of the resultant Co3O4 NDs/NCN hybrid are sys-tematically investigated, and the effect of salt template on the preparation of products is also deeply ex-plored. It is surprisingly found that the introduction of NaCl template promotes the formation of Co3O4 , which is different from what has been reported previously. In addition, the added NaCl template can be used to regulate the microstructure of Co3O4 NDs/NCN hybrid, which displays unique micromorphology (Co3O4 NDs anchored into 2D NCN), successful N doping in carbon matrix, Co-N-C bond between two components and much increased specific surface area. As a result, this hybrid shows excellent lithium storage performance when used as the anode for LIBs, which can be comparable to those previously re-ported Co3O4/C hybrid anodes. Clearly, this work offers a good reference for the construction of low-cost and high-performance TMO/carbon LIBs anodes.
