In this study, for electrochemical determination of hydrogen peroxide and investigation of its sensor performance, polythiophene doped AG@RGO 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 Ag@rGO catalyst modified with polythiophene is higher sensitivity compared with unmodified Ag@rGO catalyst. . Limit detection value (LOD) was obtained as 0,15mM and 0,033mM (S/N=3) for Ag@rGO and Ptyf-Ag@rGO, 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 Ag@rGO.

Politiyofen Katkılı Ag@rGO-GC Elektrodunda H2O2’nin Elektrokimyasal Tayini

Öz

Bu çalışmada hidrojen peroksitin elektrokimyasal tayini için politiyofen katkılı Ag@rGO 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 Ag@rGO’nun katkısız Ag@rGO’ ya kıyasla hidrojen peroksite karşı daha hassas olduğu elektrokimyasal ölçümler sonrası anlaşılmıştır. Limit dedeksiyon değeri (LOD) Ag@rGO ve Ptyf-Ag@rGO için sırasıyla 0,15mM ve 0,033 mM (S/N=3) olarak elde edilmiştir. Bununla birlikte politiyofen sadece LOD değerini düşürmekle kalmamış, Ag@rGO için yapılan ölçümlerdeki gürültü sinyallerini azaltarak daha kararlı bir akım gözlenmesine de katkı sağlamıştır
