Abstract
Electrochemical synthesis of gold nanoparticles on the surface of glassy carbon electrode and preparation of GNPs in aqueous solution using ceftriaxone as an innocuous stabilizing reagent were proposed. The gold nanoparticles were characterized by scanning electron microscopy, transmission electron microscopy, infrared spectrometry, UV spectrophotometry, powder X-ray diffraction, and cyclic voltammetry. The catalysis of gold nanoparticles on the glassy carbon electrode for dopamine was demonstrated. The results indicate that the modified electrode has an excellent repeatability and reproducibility. The relationship between the molecular structure and the dispersion of GNPs on the surface of GCE as well as the catalysis of GNPs for dopamine was discussed.
Highlights
Gold nanoparticles (GNPs) have been widely used in the fields of physics, chemistry, biology, medicine, and material science [1]
The GNPs were deposited at a voltage of −0.2 V for 30 s on the surface of glassy carbon electrode (GCE) that was immersed in the mixture of HAuCl4 (2.0 mg mL−1), H2SO4 (0.5 M), and ceftriaxone sodium (0.4 mg mL−1), and washed in doubly distilled water
The sensitivity of GNP/GCE for dopamine is lower than that GNP/DWCNT/GCE
Summary
Gold nanoparticles (GNPs) have been widely used in the fields of physics, chemistry, biology, medicine, and material science [1]. Ceftriaxone as an innocuous stabilizing reagent was used for electrochemical synthesis of GNPs on the surface of glassy carbon electrode (GCE) and preparation for GNPs in aqueous solution for a stable sensor, DFTB3LYP/6-31G (d, p) was carried out to study the molecular structure and the properties of ceftriaxone.
