Templated synthesis of 2D TiO₂ nanoflakes for durable lithium ion batteries

Abstract

In this work, the 2D TiO2 nanoflakes were prepared by employing MXene as sacrificial template for durable lithium ions batteries (LIBs) anode. Essentially, the high crystalline anatase TiO2 nanoparticles compacted...

3D hierarchical Ti3C2/TiO2 composite via in situ oxidation for improved lithium-ion storage

“…Conversely, samples calcined under high-temperature treatment in an air atmosphere only have the characteristic peak of TiO 2 , indicating that the MXene precursor was oxidized into TiO 2 materials. 19 This finding indicates the successful fabrication of a TiO 2 /Ti 3 C 2 MXene composite with various structures via effective partial thermal oxidation of the Ti layer in Ti 3 C 2 MXene at high temperatures.…”

“…S2a, ESI †), which due to the typical layered T 3 C 2 nanosheets offers a suitable derivative template to regulate the growth of TiO 2 nanocrystals. 19 Fig. 2b and Fig.…”

Two-dimensional LiTi2(PO4)3 flakes for enhanced lithium ions battery anode

“…The 2D TiO 2 nanoflakes as the template was prepared according to our previous work [ 27 ]. Firstly, 16 mg Li 2 CO 3 , 142.16 mg (NH 4 )H 2 PO 4 and 65 mg 2D TiO 2 nanoflakes were ground evenly in a mortar for 5 min to obtain homogenous mixture.…”

S- and Cl-functionalized Nb2C MXenes as novel anode materials for sodium-ion batteries: a first-principles study

“…22 MXenes have shown promise in electrochemical energy storage applications due to their high electrical conductivity, large surface areas and excellent structural stability. [23][24][25][26][27][28] Recent theoretical investigations and experiments suggest that the energy storage capacities of MXenes strongly depend on the surface terminal functional groups. [29][30][31][32] Therefore, it is of great significance to study the storage capacities associated with surface terminal functional groups to further understand the energy storage mechanisms of MXenes.…”
