Newly designed bioanode for glucose/O-2 biofuel cells to generate renewable energy

WOS: 000525455500012TARAMASCOPUSTARAMAWOSA copolymer poly(methyl methacrylate-co-vinylferrocene) was synthesized and used for the first time in a biofuel cell design. Bioanaode enzyme glucose oxidase and biocathode enzyme bilirubin oxidase were physically immobilized onto the copolymer-modified electrodes. Characterization studies were conducted by scanning electron microscopy, carbon-13, fourier transform infrared and hydrogen-1 nuclear magnetic resonance, and cyclic voltammograms. The designed biofuel cell was operated with linear sweep voltammetry. The maximum current was at 45 degrees C with 120 mu g of polymer amount. An improved power density of 323 mu W cm(-2) that is higher than other ferrocene-based fuel cells was obtained with 10-mM glucose at 0.4 V with the designed bioanode.Zonguldak Bulent Ecevit UniversityBulent Ecevit University [BEU-2013-77047330-01]; Bulent Ecevit University Research FundBulent Ecevit University [BEU-2013-77047330-01]; Scientific & Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [112Y100]Zonguldak Bulent Ecevit University, Grant/Award Number: BEU-2013-77047330-01; Bulent Ecevit University Research Fund, Grant/Award Number: BEU-2013-77047330-01; Scientific & Technological Research Council of Turkey (TUBITAK), Grant/Award Number: 112Y10
