摘要
Abstract
The design of het-eroatom-doped porous carbon ma-terials integrated with metal oxide nanostructures has emerged as an efficient approach for improving the electrochemical performance of su-percapacitors.A green and cost-ef-fective method is reported for the fabrication of a hierarchical porous carbon composite from bacterial cel-lulose(BC),lignosulfonic acid(LS),and polypyrrole(PPy).LS serves as both an anchoring agent and a soft molecular template,directing the oxidative polymerization and uni-form deposition of PPy onto the BC nanofibers in the presence of FeCl3 as the oxidizing agent.Subsequent carbonization under a nitrogen atmosphere results in the formation of an N/S co-doped carbon framework decorated with Fe3O4 nanoparticles,which is denoted C-BCLP.For comparis-on,a control composite consisting of BC and PPy without LS was carbonized to produce C-BCP.X-ray diffraction patterns confirms the synthesis of Fe3O4 nanoparticles and the preservation of the fibrous carbon structure.Electron microscopy shows that C-BCLP has a highly porous and conductive network with a homogeneous distribution of C,O,N,S and Fe elements.Be-cause of the combined effects of hierarchical porosity,heteroatom doping,and Fe3O4 incorporation,the C-BCLP electrode has high specific capacitances of 338.3 F g-1 at 1 A g-1 and 191.6 F g-1 at 10 A g-1.In addition,it has excellent cycling stability,re-taining 99.1%of its initial capacitance after 10 000 charge-discharge cycles,outperforming the C-BCP electrode.The work suggests a promising way to develop next-generation high-performance supercapacitors.关键词
