Sandwich-Like Fe&TiO2@C Nanocomposites Derived from MXene/Fe-MOFs Hybrids for Electromagnetic Absorption

Deng Baiwen,Xiang Zhen,Xiong Juan,Liu Zhicheng,Yu Lunzhou,Lu Wei

Sandwich-like laminated Fe&TiO 2 @C nanocomposites were successfully prepared from the MXene–MOFs hybrids. A broad effective bandwidth of 6.5 GHz at a thickness of only 1.6 mm was achieved.

Vapor pressure-assisted synthesis of chemically bonded TiO2/C nanocomposites with highly mesoporous structure for lithium-ion battery anode with high capacity, ultralong cycling lifetime, and superior rate capability

Meisheng Han,Yongbiao Mu,Fu Yuan,Xuedong Bai,Jie Yu

To date, development of a lithium-ion battery anode with high capacity, long cycling life over ten thousands of cycles, and fast lithium ion storage within a few seconds for each cycle is still a challenge. Here, a highly mesoporous TiO 2 /C nanocomposite consisting of ultrathin carbon layers tightly coating on the surface of anatase TiO 2 nanocrystals with an average size of 20 nm via interfacial chemical bonds of Ti-O-C is obtained by a simple and facile vapor pressure-assisted synthesis route that pyrolysis of the solution of tetrabutyl orthotitanate tetramer dissolved in ethanol in a sealed vessel. As anode for lithium ion battery , the TiO 2 /C nanocomposite shows a reversible capacity of 630.3 mAh g −1 at 0.5C after 400 cycles, which is unprecedent for the ever reported TiO 2 /C electrode at similar cycle number. Besides, the TiO 2 /C nanocomposite also exhibits ultralong cycling lifetime (over 10000 cycles without capacity loss at 120C) and ultrahigh rate capability (20.5 mAh g −1 at 144C). The outstanding lithium ion storage performances are ascribed to its unique structures, i.e., ultrathin carbon coating, ultrasmall TiO 2 particles, the formation of interfacial chemical bonds of Ti-O-C, and highly mesoporous structure.
