CO2 outperforms KOH as an activator for high-rate supercapacitors in aqueous electrolyte

Advancing mesoporous carbon synthesis for supercapacitors: a systematic investigation of cross-linking agent effects on pore structure and functionality

“…Existing studies have confirmed this phenomenon by improving the pore network connectivity through additional activation processes, especially CO 2 activation, which can effec-tively unblock and expand the existing porosity, widen narrow mesopores and thus the desorption rate can be enhanced during fast charging/discharging. 26,50 Consistent with the CV test, all MC electrodes demonstrated symmetric triangular galvanostatic charge-discharge profiles with fairly linear slope (Fig. 4d), which is a typical feature of EDLCs.…”

Mesoporous Carbon-Based Materials: A Review of Synthesis, Modification, and Applications

“…A typical chemical activation consists of the thermal decomposition of carbon precursor impregnated with suitable chemical agents at temperatures ranging from 400 • C to 700 • C [43]. The most widely used industrial activating agents in the chemical activation process are zinc chloride (ZnCl 2 ), aluminum chloride (AlCl 3 ), magnesium chloride (MgCl 2 ), sodium hydroxide (NaOH), potassium hydroxide (KOH), sodium carbonate (Na 2 CO 3 ), and phosphoric acid (H 3 PO 4 ) [43,44]. The type of chemical agent is one of the important and effective parameters of the mechanism and temperature of the activation process.…”

Asymmetric N, P‐Coordinated Single‐Atomic Fe Sites with Fe2P Nanoclusters/Nanoparticles on Porous Carbon Nanosheets for Highly Efficient Oxygen Electroreduction

“…The specific surface areas of the resultants FeNC, FePNC‐N, and FePNC are calculated to be 240, 560, 300 m 2 g −1 , and the calculated pore size distribution according to density functional theory model are in the range of 0.3–1.3 nm, verifying the microporous structures of all the resultant catalysts. [ 13 ] Besides, typical type IV isotherm hysteresis can be observed for all the resultant catalysts, revealing the presence of mesoporous structures, which has been reported to be facilitate the improvement in the ORR performance.
