Conductive metal‐organic frameworks (MOFs) are promising electrode materials for supercapacitors (SCs) because of their tunable structures, high specific surface areas, and superior conductivity. However, it remains challenging to develop conductive MOFs for organic SCs and the role of metal ions in the electrochemical performance of MOFs is still unclear but is shown to be a key factor in determining MOFs performance. Herein, two high‐performance ultra‐thin redox conductive 2D MOFs (>6000 S m−1) for SCs are prepared, and the effects of metal ions on the capacitive performance of MOF electrodes are investigated. Co2+ and Mn2+ with the same ligand provide two MOFs featuring almost the same structures and specific surface areas but show great differences in electrochemical performance except that both MOFs exhibit outstanding electrochemical performance and good cycling stability with a capacity retention of >85% after 10 000 cycles. Different metal ions endow the two MOFs with different redox behaviors, conductivities, and energy levels, where Co‐MOF shows superior specific capacity compared to Mn‐MOF. This work expands the possibility of the use of MOFs in SCs and gives insight into the roles of metal ions in MOFs.

“…Therefore, combinations of different methods are necessary to measure hazardous chemicals or ions at low level (Table 1). [101][102][103][104][105] Basic unresolved issues are related to the amount, speciation, location, mechanisms of changes upon detection, environmental changes, or onset of disease. Accordingly, studies related to the detection of hazardous chemicals present in solutions at low levels could be explored for the detection of various analytes in future.…”

The success of MOFs has driven their development as a new tool for sensing analytes including toxic chemicals. [19][20][21] The MOF sensors can be applied in both environmental and biological systems. [22] The MOF sensor field has been established with the development of sensors for different metal ions, anions, and molecules. [23,24] The potential application of MOF sensors to the detection of heavy metal ions, toxic anions, and other hazardous species is of great interest. [25,26] Specifically, luminescence technology has allowed the roles of various MOF sites in analyte capture to be easily studied. [27][28][29] The precise use of MOFs is potentially a good tool for analyte detection. Furthermore, MOFs have been established as potential materials for selective, fast, and portable tools for sensing toxic chemicals, with the advantage of light-emitting properties. [30,31] Interestingly, these sensing models can operate in water and are pH stable with high efficiency. [32] Furthermore, MOFs are wellknown materials for the degradation of toxic chemicals. [33,34] Several reports have been published on MOF sensors for toxicant chemicals, such as metal ions, anions, organic solvents, pesticides, nitroaromatic compounds (NACs), chemical warfare agents, [35] and others. [36][37][38] Some reviews have summarized applications of MOFs in sensing and detection probes for ions and volatile organic compounds, [39] and MOF sensors in pesticide detection and absorption with their classification. [40] Others have summarized and analyzed interactions between hazardous compound adsorbates and MOFs. [41,42] The stability and applications of MOFs have been summarized by the research groups of Ding and coworkers. [43] Pehlivan and et al. summarized the role of fluorescence resonance energy transfer in elucidating molecular interactions utilized in biosensing tools. [44,45] Besides luminescence sensing, the reviewers summarized the progress of MOFs relevance in the various area including environment and medical science. [46] Recently, Liu and coworkers summarized the progress of MOFs and discussed the remaining challenges in drug delivery, [47] Garcia and coworkers studied and compared the MOFs as photocatalysts with common inorganic photocatalysts, [48] and Manos and coworkers studied and summarized MOFs challenges and prospects for ion-exchange and sorption applications. [49] Despite these meaningful reviews, the factors responsible for signal changes, mechanisms, and limits of detection have Mechanistic studies of materials able to detect hazardous and toxic chemicals, such as common organic solvents, pesticides, and nitroaromatic compounds (NACs), are critically important owing to the threat they pose to humans and the environment. Recently, porous luminescent metal-organic frameworks (MOFs) with multifunctional sites, high surface areas, and structural tunability have emerged as sensory devices for the detection of hazardous and toxic chemicals. Herein, recent progress regarding the mechanistic behavior of MOF sensors in the det...

“…They also found Co-H 6 TATAT and Co-CTAB-6 retained 64.04% and 77.92% of the original capacitance value after 3000 cycles, respectively, demonstrating the positive effect of CTAB. Developing MOFs with 2D structures can also be regarded as a morphology-controlling technique [ 59 , 60 ]. Deng and co-workers [ 61 ] recently proposed a novel MOF//MOF strategy, like piecing together a puzzle, by which two kinds of 2D MOFs with specific functions are simultaneously integrated into one homogeneous layered MOF with improved electrochemical performance ( Figure 3 ).…”

Supercapacitors (SCs), one of the most popular types of energy-storage devices, present lots of advantages, such as large power density and fast charge/discharge capability. Being the promising SCs electrode materials, metal–organic frameworks (MOFs) and their derivatives have gained ever-increasing attention due to their large specific surface area, controllable porous structure and rich diversity. Herein, the recent development of MOFs-based materials and their application in SCs as the electrode are reviewed and summarized. The preparation method, the morphology of the materials and the electrical performance of various MOFs and their derivatives (such as carbon, metal oxide/hydroxide and metal sulfide) are briefly discussed. Most of recent works concentrate on Ni-, Co- and Mn-MOFs and their composites/derivatives. Conclusions and our outlook for the researches are also given, which would be a valuable guideline for the rational design of MOFs materials for SCs in the near future.
