论文摘要
Gold-copper alloy nanoparticles (AuCu NPs) were electrodeposited on a graphene – ionic liquid composite film (EGN-IL). The AuCu NPs showed high electrocatalysis to the oxidation of hydrazine with a catalytic reaction rate constant of about 5.0×104 mol/Ls. In phosphate buffer solutions (pH 6.8) the oxidation current of hydrazine at 0.15 V (vs. SCE) at the resulting electrode (AuCu-EGN-IL/GCE) was linear to its concentration in the range of 0.2–110μM with a sensitivity of 56.7μA/mM, and the detection limit was 0.1μM(S/N=3). The electrode was successfully applied to the determination of waste water.
