Özet:

 In this study, for electrochemical determination of hydrogen peroxide and investigation of its sensor performance, polythiophene doped AGRGO was synthesized in a two-step. To characterize synthesized catalysts field emission microscopy FESEM, energy-dispersive X-ray spectrometer EDX, X-ray Powder Diffraction XRD, and Uv-vis spectroscopy measurements were performed. On the other hand, electrochemical properties of catalysts were investigated by cyclic voltammetry CV and amperometric methods. It was noticed that AgrGO catalyst modified with polythiophene is higher sensitivity compared with unmodified AgrGO catalyst. . Limit detection value LOD was obtained as 0,15mM and 0,033mM SN3 for AgrGO and Ptyf-AgrGO, respectively. Additionally, polythiophene not only reduced the LOD value, but also contributed to the observation of a more stable current by reducing the noise signals in the electrochemical measurements for AgrGO.

 Bu çalışmada hidrojen peroksitin elektrokimyasal tayini için politiyofen katkılı AgrGO iki aşamada sentezlenerek sensör performansı incelenmiştir. Hazırlanan katalizörlerin karakterizasyonu alan emisyonlu taramalı elektron mikroskobu FESEM , enerji dağılım X-ışını spektroskopisi EDX , X-ışını kırınım spektroskopisi XRD ve görünür bölge UV-vis spektroskopisi ile gerçekleştirilmiştir. Diğer taraftan katalizörlerin elektrokimyasal özellikleri, dönüşümlü voltametri CV ve amperometrik yöntem ile incelenmiştir. Politiyofen ptyf katkılı AgrGOnun katkısız AgrGO ya kıyasla hidrojen peroksite karşı daha hassas olduğu elektrokimyasal ölçümler sonrası anlaşılmıştır. Limit dedeksiyon değeri LOD AgrGO ve Ptyf-AgrGO için sırasıyla 0,15mM ve 0,033 mM SN3 olarak elde edilmiştir. Bununla birlikte politiyofen sadece LOD değerini düşürmekle kalmamış, AgrGO için yapılan ölçümlerdeki gürültü sinyallerini azaltarak daha kararlı bir akım gözlenmesine de katkı sağlamıştır.
