description | [Image: see text] In this study, an eco-friendly strategy was used to prepare a novel SrTiO(3)/Ag/rGO composite. A SrTiO(3)/Ag/rGO composite-modified screen-printed carbon electrode (SPCE) was applied for the electrochemical detection of 4-nitrophenol. A simple ultrasonic method with an ultrasonic frequency of 20 kHz was used for the synthesis of SrTiO(3)/Ag/rGO composite material. The obtained SrTiO(3)/Ag/rGO composite was characterized by X-ray diffraction, Fourier transform infrared, Raman spectroscopy, field emission electron microscopy, and UV–visible spectroscopy. Electrochemical impedance spectroscopy was used to determine the electrical conductivity of the SrTiO(3)/Ag/rGO composite. The electrochemical properties of the modified electrode were studied using cyclic voltammetry as well as linear sweep voltammetry techniques. In comparison to SrTiO(3)/SPCE, SrTiO(3)/Ag/SPCE, and SrTiO(3)/rGO/SPCE electrodes, SrTiO(3)/Ag/rGO/SPCE demonstrates a considerable increase in 4-nitrophenol redox peak current. At optimum conditions, a large linear response range of 0.1–1000 M, with a relatively low limit of detection (0.03 M), outperforms the previously published modified electrode for 4-nitrophenol. Moreover, the SrTiO(3)/Ag/rGO/SPCE electrode-based 4-nitrophenol sensor is distinguished by good selectivity, high stability, and repeatability. Furthermore, SrTiO(3)/Ag/rGO/SPCE contributed to the detection of 4-nitrophenol in river water and drinking water with the recovery range from 97.5 to 98.7%. The experimental finding was supported by density functional theory calculation. |
