Abstract

Gold−platinum nanoparticles (AuPt NPs) were fabricated on chitosan (Ch)−ionic liquid (i.e., trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide, [P(C6)3C14][Tf2N]) film by using an ultrasonic electrodeposition method for the first time. Ch acted as an adsorbent for the metal ions, and [P(C6)3C14][Tf2N] played a dual role of matrix and stabilizer in the formation of the nanoparticles. The obtained AuPt NPs were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. It was found that they were well-dispersed on the composite surface, and their diameters were 10−20 nm. Furthermore, they exhibited the features of an alloy, and the atomic ratio of Au/Pt in the alloy NPs was close to the concentration ratio of AuCl4−/PtCl62− in the solution. Electrochemical observation showed that the AuPt−Ch−[P(C6)3C14][Tf2N] modified glassy carbon electrode (GCE) had a large electroactive surface area and small electron transfer resistance. When the ratio of AuCl4−/...
