Application of Mg-Al-LDH@MgFe2O4 Nanocomposite Supported on Gold Micron-Dendrites as an Efficient Electrocatalyst for Ethanol Oxidation

Mg-Al-LDH@MgFe 2 O 4 nanocomposite was synthesized and was applied to enhance efficiency of gold micron-dendrites/glassy carbon electrode (Mg-Al-LDH@MgFe 2 O 4 /AuNDs/GCE) for oxidation of ethanol. Based on the results, Mg-Al-LDH@MgFe 2 O 4 /AuNDs showed a current density of 29.4[Formula: see text]mA cm[Formula: see text], 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@MgFe 2 O 4 /AuNDs catalyst exhibits an excellent potential for application in alkaline ethanol fuel cells.
