Recent progress of MOF/MXene-based composites: Synthesis, functionality and application

Photocatalytic dehydrogenation of ammonia borane over Ti3C2/MOF-supported Pd-doped Co nanoparticles

“…1d), due to the higher crystallinity of the MOF than Ti 3 C 2 (JCPDS 52-0875). 35 The XRD patterns of CoPd@UiO-66-NH 2 and CoPd/TUNS closely resembled that of Co 30 Pd@TUNS (Fig. S9, ESI†).…”

“…S14, ESI†). It could be attributed to the occurrence of coordination interactions between Ti ions of Ti 3 C 2 and the carboxyl group in the ligand of BDC-NH 2 during the in situ synthesis, 35,39 along with the partial oxidation of Ti 3 C 2 . 40 The characteristic Co 2p spectrum was deconvoluted into the peaks at 779.8, 795.5, 781.1, and 796.9 eV, assigned to Co( ii ) 2p 3/2 , Co( ii ) 2p 1/2 , Co( iii ) 2p 3/2 , and Co( iii ) 2p 1/2 , respectively.…”

Recent advances and promise of MXene-based composites as electrode materials for sodium-ion and potassium-ion batteries

“…To address the aforementioned challenges, extensive research has been conducted on the rational design and the selection of electrode composite materials. Unlike conventional 2D nanomaterials such as graphene, 36 borophene, 37 silicon, 38 and black phosphorus, 39 MXenes exhibit a wide range of chemical compositions and atomic-scale structural arrangements, 40,41 resulting in unique properties including metallic conductivity, 42,43 adjustable band gaps, 44 a substantial redox-active surface area, 45,46 remarkable mechanical stability, 47,48 and flexibility. 49,50 MXene is predominantly found in two forms: multilayer and single-layer structures.…”

Revealing Interstitial Diffusion and Vacancy Diffusion Kinetics of Battery-like Electrodes for High-Performance Pseudocapacitors

“…The energy and climate crisis caused by fossil energy depletion and greenhouse gases emission has led to an urgent need for sustainable energy sources. − However, energy storage is vital to solving the instability problem of these sustainable energies. Due to their capacity to store charge through quick and reversible oxidation–reduction events on or near the surface of active materials, pseudocapacitors are among the most promising types of energy storage devices. , In pseudocapacitance, ions are embedded in redox-active materials without any crystal phase transition.…”
