Electrochemical determination of 2,4-dichlorophenol by using a glassy carbon electrode modified with molybdenum disulfide, ionic liquid and gold/silver nanorods

Abstract: Molybdenum disulfide (MoS) was used as an electrically conductive skeleton and functionalized with an ionic liquid and gold/silver nanorods. The resulting composite was characterized by scanning electron microscopy, transmission electron microscopy and UV-vis spectroscopy. The composites were used to modify a glassy carbon electrode (GCE) to obtain a sensor for 2,4-dichlorophenol (2,4-DCP). The results show that the oxidation power and electrocatalytic activity of the modified GCE towards 2,4-DCP are enhanced … Show more

“…6 (inset (a)), oxidation peak currents increased linearly with the increase of scan rate with the regression equation i p,a ¼ 0.0052 Â n + 0.1966 (R 2 ¼ 0.9967), which suggests an adsorption controlled kinetic process on the modied electrode surface Cu-BTC/ ErGO/GCE. 9,11,12 As seen in Fig. 6, the oxidation peak potential (E p,a ) slightly shied to more positive potentials with the increasing of the scan rate.…”

“…MoS 2 is a typical dichalcogenide, which attracts wide interests in numerous fields, such as hydrogen catalysis and storage, capacitors, and electrochemical device [36] , [37] . However, because the conductivity of MoS 2 is still lower than that of carbon-based materials, little attention has been paid to the application of MoS 2 as an electrode material for sensors [38] .…”
