Abstract :
Here we report a nano-size catalyst-enhanced enzymatic bioanode for glucose biofuel cells. The bioanode was constructed by coating a crosslinked mixture of glucose oxidase (GOx), 2,5-dihydroxybenzaldehyde (DHB), bovine serum albumin (BSA) and glutaraldehyde on a MWCNT-modified screen printed carbon electrode (SPCE). By presenting Ru-supported CMK-3 (Ru-CMK-3) in the bioanode, the biofuel cell´s power output was significantly enhanced and could reach 60 W·cm-2 at 25°C. And we found that the enhancement was attributed to CMK-3 or Ru-CMK-3-catalyzed oxidation of gluconic acid. Therefore, Ru-CMK-3 can work synergistically with GOx and achieve more complete oxidation of glucose in a biofuel cell.
