The performances of graphene oxide (GO) and graphene-platinum hybrid nanoparticles (Gr-Pt hybrid NPs) were compared for biofuel cell (BFC) systems. This is the first study that constitutes these nanomaterials in BFC systems. For this purpose, fabricated bioanodes were combined with laccase modified biocathode in a single cell membraneless BFC. Power and current densities of these systems were calculated as 2.40 mu W cm(-2) and 211.90 mu A cm(-2) for GO based BFC and 4.88 mu W cm(-2) and 246.82 mu A cm(-2), for Gr-Pt hybrid NPs based BFC. As a result, a pioneer study which demonstrates the effective performances of combination of graphene with Pt was conducted. (C) 2015 Elsevier B.V. All rights reserved.
