Abstract
Surface modification of a carbon cloth anode by screen-printing rGO and APPJ is promising for manufacturing large-scale MFC stacks.
Highlights
Microbial fuel cells (MFCs) are promising for the generation of bioelectricity via the treatment of wastewater, because they can convert chemically bound energy into biomass-based electricity with the help of electrochemically active bacteria.[1,2,3,4] It has been demonstrated that the surface characteristics of the anode electrodes are critical to the performance of microbial fuel cells (MFCs).[5]
This study investigated the surface and electrochemical properties of carbon cloth electrodes surface-modi ed by screen printing of reduced graphene oxide (rGO) and atmospheric-pressure plasma jet (APPJ) treatment for applications in MFCs
The X-ray photoelectron spectroscopy (XPS) results showed the presence of abundant carbonyl, carboxyl, and ammonium hydrophilic functional groups on the surface of the rGO & APPJtreated carbon cloth
Summary
Microbial fuel cells (MFCs) are promising for the generation of bioelectricity via the treatment of wastewater, because they can convert chemically bound energy into biomass-based electricity with the help of electrochemically active bacteria.[1,2,3,4] It has been demonstrated that the surface characteristics of the anode electrodes are critical to the performance of MFCs.[5] Among various types of electrodes, carbonaceous electrodes have gained much attention and shown considerable potential in MFC applications. Surface modi cations of the carbonaceous electrodes are inevitably needed to enhance the power performance of MFCs.[7,8,9,10,11,12,13]
