Micro-cubic monolithic carbon cryogel electrode for direct electron transfer reaction of fructose dehydrogenase

Micro-cubic monolithic carbon cryogel (CCG) electrode was fabricated for the electrochemical fructose dehydrogenase (FDH) reaction. The CCG can adsorb a sufficient amount of FDH even inside the CCG structure. FDH inside the CCG worked well as an electrocatalyst for D-fructose oxidation. An extremely high catalytic current density as large as 0.6 A/cm(3) was achieved under stirring condition. (C) 2012 Elsevier B.V. All rights reserved.
