基于木薯秸秆制备三维多孔碳及其在微生物燃料电池中的应用
Fabrication of three-dimensional porous carbon from cassava straw and application for MFCs
摘要
Abstract
Microbial fuel cells (MFCs) are emerging as an energy conversion device to directly harvest electricity energy from wastewater,of which the power density is relative low,which limited its applications to a great degree.The anode material is crucial for the improvement of power density and the energy conversion efficiency of MFCs.In this study,an advanced three-dimensional (3D) carbon anode with macropore structure was obtained by the one-step carbonization of cassava straws which are agricultural solid residues.The morphology of the 3D porous carbon (3DPC) was observed using scanning electron microscope (SEM).The results showed that the 3DPC consists of sieve-like tube structure with macropore,which is beneficial for biomass loading and mass transfer.The electrochemical performance of the 3DPC was measured by electrochemical impedance spectroscopy (EIS),cyclic voltammetry (CV) as well as dual-chamber microbial fuel cells (MFCs) device.It was found that the 3DPC obtained at 800℃ had the best electrochemical activity,and the highest power density was as high as 73.0W/m3,which was 3.7-fold higher than that of commercial carbon paper.This study provided new ideas and methods for the construction of highly efficient biochemical system electrode materials.关键词
