Aging of 2D MXene nanoparticles in air: An XPS and TEM study

Interfacial modulation to achieve low lattice thermal conductivity and enhanced thermoelectric performance in n-type Mg3(Sb, Bi)2-based materials via graphene and MXene

“…2(b)), four types of peaks can be analyzed in Ti 2p orbitals: Ti–C (∼462.4 eV), Ti–O (∼464.4 eV), Ti–F (∼466.1 eV) and TiO (∼467.5 eV). 31,32 More specifically, the Ti–C and Ti–F bonds can confirm the existence of MXene and are attributed to the C–TiO bonds in Ti 3 C 2 T x and Ti–F bonds etched from HF, respectively. Additionally, the presence of Ti–O and TiO bonds in the x = 0.6 M sample indicates a gradual oxidation of the MXene to TiO 2 , 27 which should be considered and reduced to minimize deterioration during the synthesis process.…”

MXene-BN-Introduced Artificial SEI to Inhibit Dendrite Growth of Lithium Metal Batteries

“…The F 1s spectrum of MXene5-BN5-Li showed two binding energy peaks at 689 and 685 eV, ascribed to the Li−F bond of LiF and LiTFSI, suggesting the formation of LiF. 45,46 Moreover, as shown in Figure S16, Li−F and Li−N bonds were observed in the Li 1s spectrum of MXene5-BN5-Li, confirming the formation of the LiF−Li 3 N SEI layer. 46 In addition, the Li 1s spectrum showed the presence of a Li−B bond.…”

High-Efficiency Electromagnetic Interference Shielding from Highly Aligned MXene Porous Composites via Controlled Directional Freezing

“…Figure h shows the F 1s spectrum of the MSC 0.5 . The peaks located at 685.5 and 687.1 eV correspond to F–Ti and F–C, respectively, demonstrating the presence of terminal fluorine in the PCMs . From the above high-resolution XPS spectra, it can be seen that the MSC 0.5 consists of CO, hydroxyl, and F groups to act as local dipoles, which interact with the incident electromagnetic waves to cause dipole polarization, and this helps to improve the electromagnetic shielding performance .…”
