摘要
Recently, many efforts have been made to replace Pt using carbonaceous materials such as carbon nanotubes, porous carbon, graphe, carbon fibers, and carbon black in the counter electrodes(CEs) of dye-sensitized solar cells(DSSCs) and electrode materials(EMs) of electrochemical capacitors(ECs) owing to their low cost, good electrochemical performance and high conductivity.A simple and low cost method to synthesis porous carbon materials from waste biomass was developed.Three kinds of porous carbon(hydrochar, pyrolytic carbon and activated carbon) materials have been used as CEs of DSSCs and EMs of ECs in this work.These electrodes all showed an excellent electrocatalytic activity for the reduction of I_3~- to I~- in the electrolyte, achieving wonderful conversion efficiency.Especially, the activated carbon exhibited a rather high electrochemical storage capacity with a specific capacitance of 365 F g~(-1) at 1 A g~(-1) and also revealed a high rate capability with capacitance retention of 81% even at 20 A g~(-1) as well as a high cycling stability with about 97% maintained after 5,000 charge-discharge cycles.
