Converting furfural residue wastes to carbon materials for high performance supercapacitor
文献摘要：
Sustainable development based on the value-added utilization of furfural residues(FRs)is an effective way to achieve a profitable circular economy.This comprehensive work highlights the potential of FRs as precursor to prepare porous carbons for high performance supercapacitors(SCs).To improve the electrochemical performance of FR-based carbon materials,a facile route based on methanol pretreatment coupled with pre-carbonization and followed KOH activation is proposed.More defects could be obtained after methanol treatment,which is incline to optimize textural structure.The activated methanol treated FR-based carbon materials(AFRMs)possess high specific surface area(1753.5 m2 g-1),large pore volume(0.85 cm3 g-1),interconnected micro/mesoporous structure,which endow the AFRMs with good elec-trochemical performance in half-cell(326.1 F g-1 at 0.1 A g-1,189.4 F g-1 at 50 A g--1 in 6 mol L-1 KOH).The constructed symmetric SCs based on KOH,KOH-K3Fe(CN)6 and KOH-KI electrolyte deliver energy density up to 8.9,9.9 and 10.6 Wh kg-1 with a capacitance retention of over 86％after 10,000 cycles.Furthermore,the self-discharge can be restrained by the addition of K3Fe(CN)6 and KI in KOH electrolyte.This study provides an effective approach for high-valued utilization of FR waste.
