著者：M. Tominaga題名：High Potential Oxygen Reduction at Laccase-Modified SWCNT Electrode
for Enzyme Catalytic Fuel Cel発表情報：Abstracts of the First International Conference on Advanced Materials, (SCICON 16), Amrita Vishwa Vidyapeetham (Amrita University) ページ: IT16-IT17キーワード：概要：Efficient transformation from chemical potential to electrical energy is important for developing advanced energy conversion and storage technologies to reduce our dependence on conventional fossil fuels as energy sources. Fuel cell is a key device for the chemical-electrical energy transformation.
Enzyme catalytic fuel cells (EFCs) are based on the immobilization of redox enzymes on electrodes and their efficient electronic contact. In addition to a high catalyst loading, high power EFCs require the fast of electron transfer (ET) rates in order to achieve low potential/high current bioelectrocatalysis. This is especially the case at the cathode side where oxygen must be reduced into water in a 4H+/4e− process. For this purpose, high potential multicopper oxidases (MCOs) such as laccase (Lac) and bilirubin oxidase, have been widely studied at the surface of electrodes for the ability of their multicopper active site to reduce oxygen at low overpotentials. Recently, we have reported that an interface between Lac and single-walled carbon nanotubes (SWCNTs) displaying very fast electron transfer was achieved by modification with biosurfactant [1-5]. Furthermore, the reduction reaction of O2 was very close to the equilibrium redox potential of the O2/H2O redox couple.抄録：英語フィールド
