| Abstract: | The formation of Ru microspheres by hydrothermal treated method in tungstosilicate acid (H4SiW12O40, TSA) solution is described. The particles are characterized by X‐ray diffraction analysis (XRD) and scanning electron microscopy (SEM), respectively. The growth process of these microspheres has been examined. The results show that it is possible to synthesize and assemble other noble metal particles with unique superstructure. The characteristic catalytic behavior of the Ru microspheres is established by studying the decolorization of cango red in the presence of UV light. (© 2009 WILEY‐VCH Verlag GmbH & Co.
