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 bioanode 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 μA cm−2 to 180 μA 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 E0 = 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.
