Abstract
A facile route was introduced to generate uniform raspberry-like gold@polyaniline (AuNP@PANI) particles in the presence of sodium dodecylsulfate (SDS). The surfactant SDS played an important role in both generating a uniform structure and stabilizing these particles. Upon addition of low-molecular weight organics, the regulation on the gold architecture was realized from a compact to stretched configuration owing to the change of surface tension and a possible swell process. The catalytic activity of the raspberry-like AuNP@PANI was investigated using the reduction of 4-nitrophenol by NaBH4 and electrocatalytic oxidation of glucose as model reactions. It was found that the AuNP@PANI particles with the most stretched architecture presented the highest catalytic activity owing to their largest contact surface to the reactants.
