Özet:

 Pt micronano particles were supported on polythionine 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 PtPTH catalyst prepared under optimum conditions, SEM images were recorded. When the cyclic voltammetric behavior of bioethanol with the PtPTH 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.

 Pt mikronano parçacıkları politiyonin iletken polimer destek malzemesi üzerinde sentezlenmiş ve etanolün elektrokimyasal yükseltgenmesi için kullanılmıştır. Tiyonin, sulu çözeltiden dönüşümlü voltametri ile polimerleştirildi. Pt kompleksinin polimer film yapısına immobilize edilmesi, sulu K2PtCl4 çözeltisinden dönüşümlü voltametrik taramalar ve ardından kimyasal veya elektrokimyasal indirgeme yoluyla gerçekleştirildi. Deneysel parametreler, etanol çözeltisinde kaydedilen pik akımı değerlerine göre optimize edildi. Optimum şartlarda hazırlanan PtPTH katalizörünün fiziksel karakterizasyonu için SEM görüntüleri kaydedildi. Optimum şartlarda hazırlanan PtPTH katalizörü ile biyoetanolün dönüşümlü voltametrik davranışı incelenip sentetik etanol ile karşılaştırıldığında geliştirilen katalizörün biyoetanol yükseltgenmesi için yüksek katalitik aktivite gösterdiği ortaya çıktı.
