This paper reports the fabrication of Au nanoparticles (Au NPs)‐Ni‐Al layerd double hydroxide (LDH) composite film by one step electrochemical deposition on the surface of a glass carbon electrode from the mixture solution containing HAuCl 4 and nitrate salts of Ni 2+ and Al 3+ . Improved conductivity was obtained by Au NPs codeposited on LDH film. The synergic effect of LDHs and Au NPs dramatically improves the performance of L ‐cysteine electro‐oxidation, displaying low oxidation peak potential (0.16 V) and high current response. Thus the electrode was used to sense L ‐cysteine, showing good sensitivity and selectivity.
