Flower-like Sub-micrometer Gold Particles: Size-and Surface Roughness-controlled Synthesis and Electrochemical Characterization

摘要：

Flower-like sub-micrometer gold particles were synthesized through a simple one-step method using pdiaminobenzene as a reductant in the presence of poly (sodium 4-styrenesulfonate) in aqueous solution. The particle size with diameters ranging from 267 nm to 725 nm could be tuned by varying the molar ratio of poly(sodium 4-styrenesulfonate) to HAuCl4 (sample 1 to sample 4 in Fig. 1), which also resulted in tunable roughness. The gold particles were confirmed further by scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.
