- Abstract
Mg-Al-LDH@MgFe2O4 nanocomposite was synthesized and was applied to enhance efficiency of gold micron-dendrites/glassy carbon electrode (Mg-Al-LDH@MgFe2O4/AuNDs/GCE) for oxidation of ethanol. Based on the results, Mg-Al-LDH@MgFe2O4/AuNDs showed a current density of 29.4 mA cm − 2 , which was 1.6 times higher than that on the surface of AuNDs/GCE. Also, long-term stability of the studied electrode showed that the nanocomposite improves CO-poisoning tolerance of the AuNDs. Accordingly, the Mg-Al-LDH@MgFe2O4/AuNDs catalyst exhibits an excellent potential for application in alkaline ethanol fuel cells. In this work, the Mg-Al-LDH@MgFe2O4 was synthesized and deposited on the glassy carbon electrode which modified with Au nanoparticles. Electrocatalytic effect of modified electrode for the oxidation of ethanol was investigated. The obtained current density on the modified electrode increased about 1.6 times.
