| Abstract: |
Ferulic acid ((E)-3-(4-hydroxy-3-methoxy-phenyl)prop-2- enoic acid), FA) is a phenolic phytochemical which mostly occurs in plant cell walls. It has significant medical properties like antioxidant activity, anti-diabetic, anti-cancer, pulmonary protection[1]. It is typically determined using chromatographic and electrochemical techniques. This paper reports voltammetric sensing of FA on a TiO2-modified reduced graphene oxide (RGO) platform. RGO has found wide applications as an electrochemical sensing material due to its high surface area, high electron mobility, ease of functionalization, and high electrochemical reactivity. TiO2 is a well-studied catalyst, and its composite with RGO could enhance sensitivity and selectivity of the sensing platform. In this study, RGO, synthesized by reduction of GO with NaBH4, was treated hydrothermally with titanium isopropoxide, resulting in nanocomposites of anatase TiO2 nanoparticles with RGO, as evidenced by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and high-resolution scanning electron microscopy (HRSEM). |
