This study demonstrates the performance of a new type alcohol/O2 biofuel cell assembled by using alcohol dehydrogenase (ADH) and bilirubin oxidase (BOD) as the biocatalysts of the bioanode and the biocathode for the bioelectrocatalytic oxidation of alcohol and reduction of oxygen, respectively. To construct the bioanode and the biocathode, single-walled carbon nanotubes (SWCNTs) were used. In the bioanode, SWCNTs were used as the supporting materials for both methylene green (MG) which was used as the electrocatalyst for the oxidation of NADH and ADH. The as-constructed MG/ADH/SWCNTs-based bioanode exhibits a good activity toward the bioelectrocatalytic oxidation of ethanol. In the …
