摘要: Abstract Nanosized Ni–Al LDHs were synthesized via a hydrothermal method by using Au colloidal nanoparticles as nuclei for LDH growth, designated Au/Ni–Al LDHs. Transmission electron microscopy, X-ray diffraction and photoelectron spectroscopy used to characterize the structure morphology. N 2 physisorption was performed measure specific surface area. Electrochemical impedance cyclic voltammetry introduced investigate electrochemical properties of The average size small 10 ± 0.2 nm, high BET area obtained. conductivity improved modified glassy carbon electrode (GCE), compared GCE. Ascorbic acid model molecule study electroanalytical results exhibited that sensitive detection
