Abstract
Ternary nanocomposite of gold nanoparticles, La2Ti2O7 (LTO) and reduced graphene oxide (RGO) was synthesized by a simple hydrothermal method. Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV-vis diffuse reflectance spectra (DRS) and X-ray diffraction (XRD) were applied in the characterization of the materials. The characterization results revealed that Au nanoparticles were dispersed well on the surface of LTO/RGO. Under light irradiation, the response signal of Au-LTO/RGO for BPA detection exhibited 1.91 times higher than that of dark condition thanks to the special SPR property of Au nanoparticles. Additionally, amperometry method was more beneficial for obtaining lower LOD compared with DPVs and photocurrent methods. The obtained linear work ranges from 0.1 to 21.9 μM and the LOD was 0.03 μM (S/N=3). Ultimately, the Au-LTO/RGO sensor also displayed satisfactory results to detect BPA in real samples system.
