“…15,16 EDLCs store energy nonfaradaically or electrostatically by the adsorption/desorption of ions at the electrode–electrolyte interface forming an electrochemical double layer, and no redox reactions or chemical and compositional changes occur. 15,17,18 Carbon-related materials such as activated carbon, metal–organic framework (MOF) derived porous carbon, carbon nanotubes, carbon aerogels, etc. , store energy by the EDLC mechanism.…”

“…[12][13][14] Although pseudocapacitive materials have their own merits, their low electric conductivity, cost inefficiency, structural instability, low cycling stability, and kinetic irreversibility limit their direct practical application. 15,16 EDLCs store energy nonfaradaically or electrostatically by the adsorption/desorption of ions at the electrode-electrolyte interface forming an electrochemical double layer, and no redox reactions or chemical and compositional changes occur. 15,17,18 Carbon-related materials such as activated carbon, metalorganic framework (MOF) derived porous carbon, carbon nanotubes, carbon aerogels, etc., store energy by the EDLC mechanism.…”

“…Similarly, Kim et al prepared Fe- and N-doped porous carbon for ORR application, heterostructured porous carbon for lithium ion storage, and KOH-activated hollow ZIF-8-derived porous carbon for supercapacitor application due to the presence of a highly mesoporous structure. Kim et al synthesized Co, Fe, and N co-doped hollow carbon nanoboxes, which significantly induce the graphitization of carbon by a high carbonization process …”

Growth Control of Metal–Organic Framework Films on Marine Biological Carbon and Their Potential-Dependent Dopamine Sensing

“…In the field of electrochemical sensing, materials with hierarchical structures and large surface areas that are highly conductive are likely to have superior performance. − Nevertheless, artificial multilayered and porous materials that meet these standards are typically costlier and more difficult to be fabricated. Therefore, researchers attempted to construct low-cost and high-volume substrates by combining carbonized natural materials with functional materials such as metal–organic frameworks (MOFs). , MOFs are well known for their typical characteristics, including large specific surface areas, ultrahigh porosities, and excellent thermal and chemical stabilities. , Previously, Kim et al detailed protocols for synthesizing high-quality ZIF-8 and its modified forms of hollow ZIF-8, core–shell ZIF-8@ZIF-67, and ZIF-8@mesostuctured polydopamine, which could be widely utilized in electrochemical applications.…”
