title: Flexible carbon cloth electrode modified by hollow core-mesoporous shell carbon as a novel efficient bio-anode for biofuel cell.
abstract: A new approach is described to produce an efficient electrode material for biofuel cells using flexible carbon cloth (FCC) and hollow core-mesoporous shell carbon (HCMSC) nanospheres as bio-anode materials. The bio-electrochemical activity of glucose oxidase (GOx) enzyme adsorbed on this bio-anode was evaluated, with the maximum anodic current density varying from 80 microA cm(-2) to 180 microA cm-2 for glucose concentrations up to 5.0 mmol L(-1) for the FCC modified electrode with HCMSCs. The open circuit cell voltage was E(0) = 380 mV, and the catalytic electro-oxidation current of glucose reached 0.1 mA cm(-2) at 0.0 V versus Ag/AgCl. This new system employing HCMSC-based FCC is promising toward novel bio-anodes for biofuel cells using glucose as a fuel.
