“…In addition, to confirm the structural advantages of the porous Ti3C2/NiCo-MOF composite, N2 isotherm was employed to measure the specific surface area. The Ti3C2/NiCo-MOF-0.4 composite possesses a higher BET surface area of 60.3 m 2 g −1 than that of MXene (23.5 m 2 g −1 ) or NiCo-MOF (37.1 m 2 g −1 ) [31]. The increased surface area caused by 3D porous structures and expanded interlayer spacing between Ti3C2 sheets could offer rapid infiltration of electrolyte and more active sites for electrochemical reaction.…”

To improve Li storage capacity and the structural stability of Ti3C2 MXene-based electrode materials for lithium-ion batteries (LIBs), a facile strategy is developed to construct three-dimensional (3D) hierarchical porous Ti3C2/bimetal-organic framework (NiCo-MOF) nanoarchitectures as anodes for high-performance LIBs. 2D Ti3C2 nanosheets are coupled with NiCo-MOF nanoflakes induced by hydrogen bonds to form 3D Ti3C2/NiCo-MOF composite films through vacuum-assisted filtration technology. The morphology and electrochemical properties of Ti3C2/NiCo-MOF are influenced by the mass ratio of MOF to Ti3C2. Owing to the interconnected porous structures with a high specific surface area, rapid charge transfer process, and Li+ diffusion rate, the Ti3C2/NiCo-MOF-0.4 electrode delivers a high reversible capacity of 402 mAh g−1 at 0.1 A g−1 after 300 cycles; excellent rate performance (256 mAh g−1 at 1 A g−1); and long-term stability with a capacity retention of 85.7% even after 400 cycles at a high current density, much higher than pristine Ti3C2 MXene. The results highlight that Ti3C2/NiCo-MOF have great potential in the development of high-performance energy storage devices.

“…As a class of emerging function material, metal-organic frameworks (MOFs) were proposed by Yaghi et al [16]. Generally, MOFs possess some intriguing characteristics, containing outstanding light weight, adjustable pore size and distribution, extraordinary specific surface area, and high flexibility of the material composition [17,18]. Recently, more and more attentions have been attracted by the implantation of MOFs in energy storage areas including supercapacitors and lithium-ion batteries [19].…”

“…The performance of EES is bound up with the electrode materials driving researchers to find suitable electrode materials. MOF and COF nanosheets are considered as ideal materials and have been widely applied in EES devices [30,170,171], because they have large specific surface area and ultrathin thickness. Large specific area benefits for the electrolyte impregnation and ion storage; nanometer thickness reduces the length of ion/electron migration and facilitates ion diffusion/electronic transport, showing excellent electrochemical performance.…”

Metal-organic framework (MOF) nanosheets and covalent organic framework (COF) nanosheets as emerging porous materials nanosheets have captured increasing attention owing to their attractive properties originating from the advantages of large lateral size, ultrathin thickness, tailorable physiochemical environment, flexibility and highly accessible active sites on surface, and the applications of them have been explored in a wide range of fields. Although MOF and COF nanosheets own many similar properties, their applications in various fields show significant differences, probably due to their different compositions and bonding modes. Hence, we summarize the recent progress of MOF and COF nanosheets by comparative analysis on their advantages and limitations in synthesis and applications, providing a more profound and full-scale perspective for researchers or beginners to understand this field. Herein, the categories of preparation methods of MOF and COF nanosheets are firstly discussed, including top-down and bottom-up methods. Secondly, the applications of MOF and COF nanosheets for separation, catalysis, sensing and energy storage are summarized. Finally, based on current achievements, we put forward our personal insights into the challenges and outlooks on the synthesis, characterizations, and promising applications for future research of MOF and COF nanosheets.
