“…N‐doped porous carbons have attracted great interest due to their improved performance as electrodes in electrochemical storage, compared to their un‐doped analogous . However, the synthesis of N‐doped carbons usually requires long steps, which involve high carbonization temperature and further post‐treatment to introduce N. They can also be obtained from direct pyrolysis of N‐enriched metal‐organic frameworks (MOFs), and polymers such as the polypyrrole, polydopamine or polyacrylonitrile . However, organic precursors are less available than biomass .…”

The conversion of bio‐waste into useful porous carbons constitutes a very attractive approach to contribute to the development of sustainable energy economy, even more as they can be used in energy storage devices. Here we report the synthesis of N‐doped carbons from hydrothermal carbonization of macroalgae, Enteromorpha prolifera (EP), followed by a mild KOH activation step. The obtained N‐doped carbons exhibited surface areas of up to ∼2000 m2/g with N‐loadings varied in the range of 1.4∼2.9 at %. By modifying activation temperature, we were able to tune the surface chemistry and porosity, achieving excellent control of their properties. The specific capacitance reached values of up to 200 F/g at 1 A/g in 6 M KOH for the sample obtained at activation temperature of 700 °C (AHC‐700). The symmetric supercapacitor using the sample activated at 800 °C (AHC‐800) as electrodes exhibited the highest cycling stability of the samples studied in this work, with capacitance retention of up to 96 % at 10 A/g, even after 10,000 cycles, constituting the highest reported for biomass‐derived carbon electrodes. These results show the great potential of N‐doped carbons as electrodes for supercapacitors and confirm the excellent electrochemical properties of biomass‐derived carbons in energy storage technologies.

“…Two other reports using pyridine-containing linker or dabco (dabco = 1,4-diazabicyclo [2.2.2] octane) as N-dopant sources were published [47,48]. Two N-doped porous carbons (NPCs) derived from ([Zn(bpydc)DMA]•DMF (bpydc = 2,2 -bipyridine-5,5 -dicarboxylate, DMA = dimethyl acetamide, DMF = N,N-dimethylformamide, the abbreviation of "bpydc" is used here instead of "bpdc" to avoid any confusion with the same term for 4,4 -biphenyldicarboxylic acid) were synthesized from direct carbonization (3 h, N 2 flow) at two different temperatures (800 and 1000 • C) [47]. The NPC800 showed a higher S BET with a larger V pore as well as a higher N-dopant content than NPC1000.…”

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.

“…Instead there is clearly a synergistic effect in C-10 hybrid MOF exposing more active sites, deeper access of the electrode material to the electrolyte, and better charge transport together causing enhanced specific capacitance. The value of specific capacitance calculated for the C-10 composite was compared to the specific capacitance reported previously for other MOFs, their composites, and materials derived from MOFs based on Ni, Mn, Zr, Fe, Cu, Co, and Al, as can be seen in Table 2 [51][52][53][54][55][56][57][58][59][60].…”
