摘要: We herein report a one-step, wet-chemical approach to synthesizing gold nanoplates in large quantities via the AuCl₄^- thermal reduction process by aniline, without introducing additional capping agent or surfactant. It is found that the reduction kinetics of AuCl₄^- is greatly altered by varying the initial molar ratio of aniline to AuCl₄^-. Moreover, further investigation reveals that the insitu formed polyaniline could serve effectively as a capping agent to preferably adsorb the {111} facets of gold crystals during a slow reduction process, directing the formation of gold nanoplates.
