Özet

In this study, catalysts consisting of ruthenium (Ru95%) and cobalt (Co5%) supported on carbon nanotubes (CNTs) were prepared using the NaBH4 reduction method. After the Ru-Co/CNT catalysts were prepared, an efficient and sensitive electrochemical sensor was developed using glassy carbon electrode (GCE) modified with Ru-Co/CNT catalysts. The electrochemical behavior of Ru-Co/CNT-modified GCE electrodes was investigated using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Electrochemical results show that the GCE electrode modified with Ru-Co/CNT has a sensitivity of 0.009 mA/cm2.mM, limit of detection (LOD) 0.06 μM a limit of quantification of (LOQ) 0.18 μM for threonine. In conclusion, the results show that the Ru-Co/CNTmodified GCE electrode has been synthesized for the first time in the literature and is a promising catalyst for the sensitive detection of threonine.
