Abstract
Pt micro/nano particles were supported on poly(thionine) conducting polymer and used as catalyst for electrochemical oxidation of ethanol. Thionine was polymerized from its aqueous solution by cyclic voltammetry. Incorporation of Pt complex was carried out electrochemically by polycyclic voltammetry using K2PtCl4 as the precursor prior to reduction. Evaluation of optimum experimental parameters was done according to the obtained oxidation currents recorded in ethanol solutions with cyclic voltammetry. For the physical characterization of the Pt/PTH catalyst prepared under optimum conditions, SEM images were recorded. When the cyclic voltammetric behavior of bioethanol with the Pt/PTH catalyst prepared under optimum conditions was examined and compared with synthetic ethanol, it was revealed that the developed catalyst showed high catalytic activity for bioethanol oxidation.
