Laccase biocathodes were prepared by immobilizing a polypyrrole film containing different redox mediators (ruthenium and osmium complexes). The bioanode for EtOH,O2 MlessEBFCs was fabricated by immobilizing multiwalled carbon nanotubes, NAD+-dependent alcohol dehydrogenase enzyme (ADH), poly-methylene green, and poly(amidoamine) (PAMAM) dendrimer onto a carbon cloth platform. Maximum power density and current density were 21.0 ± 0.2 mW cm-2 and 0.15 ± 0.07 mA cm-2, respectively, in PBS (pH 6.5). Lifetime tests conducted for EtOH,O2 MlessEBFCs showed promising perspectives for their future application in miniaturized devices. 2019 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42961598008 https://www.redalyc.org/journal/429/42961598008/ https://www.redalyc.org/journal/429/42961598008/html/ https://www.redalyc.org/journal/429/42961598008/42961598008.epub https://www.redalyc.org/journal/429/42961598008/movil https://doi.org/10.26850/1678-4618eqj.v44.1SI.2019.p46-54 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.5 Vol.44 |
