Porous carbon as electrode material in direct ethanol fuel cells (DEFCs) synthesized by the direct carbonization of MOF-5

Metal-organic frameworks-derived mesoporous carbon for high performance lithium–selenium battery

“…MOFs have been recognized as very promising precursors for the synthesis of porous carbon materials, because depending on the metal and organic-ligand selected, networks with various pore shape, size, volume, chemistry can be synthesized, and the porous carbon derived from MOFs without any modification exhibits uniform porosity and porous structure [17][18][19]. Porous carbon materials derived from MOFs have been successfully applied to extensive fields, such as lithium batteries (Li-ion batteries [20], Li-S batteries [21,22] and Li-air batteries [23]), supercapacitors [24,25], fuel cells [26], and so on. However, MOFs-derived porous carbon materials were rarely investigated in lithium selenium batteries as cathode materials to improve the utilization of selenium and cycling performance.…”

Acid base co-crystal converted into porous carbon material for energy storage devices

“…Air was flushed away by continuous flow of Ar for 30 minutes. The sample was heated up to 600 °C (10 °C min -1 ) for 6 h under continuous flow of Ar gas and cooled 20 slowly to room temperature. The carbon material (0.33 g) obtained was denoted as CIN-600 with total yield of 66%.…”

“…The excellent capacitive performance of CIN-600 sample can also be attributed to its large porosity as 15 presented in gas adsorption and microscopic studies. The specific capacitance (F g -1 ) from CV curves were calculated using the following equation; C sp = (∆Q)/(∆V×m) where '∆Q' is the charge (C) integrated from the whole voltage range, '∆V' is the whole voltage (V) difference, and 'm'is the mass (g) of carbon on the 20 electrode. The calculated values of specific capacitance are given in Table S2 (supplementary information) for CIN-600 sample.…”

“…It was concluded that the sample carbonized at 800 °C displayed the highest surface area and highest specific capacitance up to 232 F g -1 at 0.1 A g -1 current density. Xu and coworkers [43] used metal-organic framework (MOF) as a template and furfuryl alcohol as a 20 precursor for the synthesis of nanoporous carbon (NPCs). The BET surface area of the NPCs fall in the range of 1140 to 3040 m 2 g -1 and the pore size distribution centered at about 3.9 nm.…”

“…Cocrystals comprise of two or more molecules known as co-crystal 20 constructors. According to the Cambridge Structural Database (CSD) survey co-crystal represents less than 0.5% published crystal structures [1].…”
