摘要：
Hollow spheres and nanospheres of Au have been prepared by a simple reaction of HAuCl4·4H2O, NaOH and (NH2OH)2·H2SO4 in the presence of gelatin. The role of gelatin and the effect of the temperature of the reaction in producing the spherical particles of Au are discussed. The products were characterized by powder X-ray diffraction (XRD), transmission electron microscopy and UV–Vis absorption spectroscopy. The sizes of the nanospheres of Au were estimated by the Debye–Scherrer formula according to the XRD spectrum.
