“…Many other reports that introduced different aromatic linkers [39][40][41][42][43] or aliphatic linkers [44][45][46] into the Zn-MOF templates were published. The former reports are further divided into two parts based on whether bdc modified linkers were employed [39,40] or not [41][42][43]. A NH 2 -bdc or 2-aminobenzene-1,4-dicarboxylic acid-based Zn-MOF (IRMOF-3) was used as a self-sacrificing template for the scalable synthesis of a hierarchical N-doped porous carbon (N-doping level = 3.3%) [39].…”

“…Zn(thip) (thip = 5-tert-butyl isophpthalate) was employed as a precursor for the preparation of 3D sponge shaped porous carbons (PCs) with interconnected hierarchical porosity as shown in Figure 2 [41]. From a single-step carbonization (2 h, Ar flow) of two different particle sized Zn-MOFs (Zn(thip)-B and Zn(thip)-S), the corresponding carbon samples (C-B-n, C-S-n, n = carbonization temperature in • C) were obtained.…”

Numerously different porous carbons have been prepared and used in a wide range of practical applications. Porous carbons are also ideal electrode materials for efficient energy storage devices due to their large surface areas, capacious pore spaces, and superior chemical stability compared to other porous materials. Not only the electrical double-layer capacitance (EDLC)-based charge storage but also the pseudocapacitance driven by various dopants in the carbon matrix plays a significant role in enhancing the electrochemical supercapacitive performance of porous carbons. Since the electrochemical capacitive activities are primarily based on EDLC and further enhanced by pseudocapacitance, high-surface carbons are desirable for these applications. The porosity of carbons plays a crucial role in enhancing the performance as well. We have recently witnessed that metal–organic frameworks (MOFs) could be very effective self-sacrificing templates, or precursors, for new high-surface carbons for supercapacitors, or ultracapacitors. Many MOFs can be self-sacrificing precursors for carbonaceous porous materials in a simple yet effective direct carbonization to produce porous carbons. The constituent metal ions can be either completely removed during the carbonization or transformed into valuable redox-active centers for additional faradaic reactions to enhance the electrochemical performance of carbon electrodes. Some heteroatoms of the bridging ligands and solvate molecules can be easily incorporated into carbon matrices to generate heteroatom-doped carbons with pseudocapacitive behavior and good surface wettability. We categorized these MOF-derived porous carbons into three main types: (i) pure and heteroatom-doped carbons, (ii) metallic nanoparticle-containing carbons, and (iii) carbon-based composites with other carbon-based materials or redox-active metal species. Based on these cases summarized in this review, new MOF-derived porous carbons with much enhanced capacitive performance and stability will be envisioned.

Metal-organic frameworks (MOFs) are deemed an attractive type of active material during electrochemical reaction processes because of their unique compositional and structural superiority, as well as the dual role as both templates and precursors to derive a large variety of functional materials for energy conversation and storage. Herein, reviewing the recent advances of MOFs and their derived functional materials as electrode materials in supercapacitors, which are classified into pristine MOFs, MOF composites, and MOF-derived functional materials, is focused on. Their synthetic routes and modification strategies are summarized and the relationship between the diversity of the architectures and compositions of MOF-based materials and their electrochemical performance is discussed. In addition, the challenges and opportunities on future research and extensive applications of MOFs and their derived functional materials are offered.
