Microwave-assisted synthesis of platelet-like cobalt metal-organic framework, its transformation to porous layered cobalt-carbon nanocomposite discs and their utilization as anode materials in sodium-ion batteries

Metal‐organic frameworks (MOFs) integrate several advantages such as adjustable pore sizes, large specific surface areas, controllable geometrical morphology, and feasible surface modification. Benefiting from these appealing merits, MOFs have recently been extensively explored in the field of advanced secondary batteries. However, a systematic summarization of the specific functional units that these materials can act as in batteries as well as their related design strategies to underline their functions has not been perceived to date. Motivated by this point, this review dedicates to the elucidation of diverse functions of MOFs for batteries, which involve the electrodes, separators, interface modifiers, and electrolytes. Particularly, the main engineering strategies based on the physical and chemical features to enable their enhanced performance have been highlighted for the individual functions. In addition, perspectives and possible research questions in the future development of these materials have also been outlined. This review captures such progress ranging from fundamental understanding and optimized protocols to multidirectional applications of MOF‐based materials in advanced secondary batteries.

“…[7] The great potential of MOFs has been found in gas separation and adsorption, [8] catalytic fields, [9] sensing platforms, [10] and others. MOFs are gradually being used in the fabrication of different energy storage devices, such as batteries [11][12][13][14][15][16][17][18][19] and capacitors. [20][21][22][23][24] However, most MOFs encounter three primary problems when used as electrode materials: low electrical conductivity, reduced exposure of active sites due to stacked morphology, and poor mechanical/chemical stability.…”

Metal–organic frameworks (MOFs) are considered potential electrode materials for lithium‐ion batteries (LIBs) in the future because of their structural diversity and high controllability. However, due to poor electrical conductivity and few exposed active sites caused by structural stacking, MOFs material is difficult to use as electrode material directly. Therefore, herein, a new preparation method is proposed. Specifically, vapors containing organic ligands reacted with porous carbon fibers loaded with metal ions under high temperature and pressure to prepare porous carbon nanofibers loaded with nanoscale Co‐MOF particles (Co‐MOF/Pcnf). Compared with the solvothermal method, the gas‐solid reaction method can limit the growth of MOFs to a certain extent. Nanoscale MOFs particles have a larger specific surface area, exposing more active sites. The introduction of porous carbon fibers enhances electrical conductivity. These properties have a positive effect on improving the performance and stability of the corresponding batteries. When used as an anode of LIBs, the Co‐MOF/Pcnf composite exhibits a specific capacity of 1036.9 mAh g−1 after 150 cycles at 0.5 A g−1 and an excellent long‐term cycling capability (820.33 mAh g−1 at 1 A g−1 after 300 cycles). This novel preparation method can provide ideas for future research on electrode materials for MOFs.

“…Microwave (MW) heating has recently gained considerable prevalence as a technique for synthesizing organic and inorganic/organic compounds. [39][40][41] In particular, microwave irradiation is an optimal method for substantially reducing the time required to synthesize porous materials. The conversion of MW radiation to heat is often uniform and efficient, enabling reduced energy consumption and minimizing the need for extensive heat transfer within a mixture.…”

Biomolecule‐incorporated metal‐organic frameworks (b‐MOFs) exhibit enhanced bioavailability and biocompatibility, making them an ideal option for use as drug delivery vehicles. While b‐MOFs possess outstanding drug loading and release capabilities, their microscale crystal sizes restrict their applicability as nanocarriers and drug delivery systems. To overcome this limitation, this paper presents a microwave‐irradiation‐based technique for the synthesis of porous adenine‐incorporated Zn‐based MOFs with particle sizes of approximately 200 nm as paclitaxel nanocarriers. The nanomaterial demonstrated a substantial paclitaxel loading capacity of 637 mg g−1. Moreover, it effectively increased the solubility of paclitaxel by 2.5‐fold compared to that of the free form. Thus, the nano MOF is a promising delivery vehicle for paclitaxel. Notably, the paclitaxel‐loaded nano MOF exhibited higher toxicity toward cancer cells than the free drug, further highlighting its potential as an effective anticancer agent.
