In this study the catalytic properties of gold nanoparticlesin electro-oxidation process of glucose, were investigated, taking into account,an influence of catalyst composition. Graphene oxide was applied andfor electro-oxidation studies of glucose, cyclic voltamperometry was used. It was found that an application of graphene oxide sheets during catalyst synthesis have an influence on gold nanoparticles (AuNPs) size andsize distribution. It was confirmed that the application of composite catalyst consisting of graphane-AuNPssignificantly changes electro-oxidation of glucose shifting the potential of oxidation to higher positive valuesand increasing oxidation current.
