Synthesis of novel urchin-like architecture Au by self-assembly coupled without template

The formation of novel urchin-like architecture Au by hydrothermal treated method in tungstosilicate acid (H4SiW12O40, TSA) solution is described. The particles are characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM), respectively. The results show that it is possible to synthesize and assemble other noble metal particles with unique superstructure with possible applications in catalysis and other fields.
