Abstract: The three-dimensional polyallylamine (PAH)-functionalized gold nanodendrites (PAH-3D-Au-NDs) were successfully synthesized through a simple, one-step electrodeposition method. SEM, TEM, energy-dispersive spectrum mapping, and X-ray photoelectron spectroscopy measurements were used to characterize the morphology, structure, and composition of PAH-3D-Au-NDs. The PAH-3D-Au-NDs were then used as the functional interface to effectively immobilize the ruthenium(III) ion through coordination interactions between the ruthenium(III) ion and PAH. The obtained RuIII/PAH-3D-Au-NDs/Au electrode showed excellent electrocatalytic activity towards iodate reduction. With the use of PAH-3D-Au-NDs, the proposed iodate electrochemical sensor displayed a fast response (less than 3 s), wide linear range (4.99×10−8 to 8.50×10−4 m), and low detection limit (1.66×10−8 m).
