Abstract
We report on the fabrication of noble metal nanoparticles loaded on the surfaces of crosslinked polycyclotriphosphazeneco44′sulfonyldiphenol PZS nanotubes of high stability PZS nanotubes were first synthesized by precipitation polymerization between hexachlorocyclotriphosphazene and 44′sulfonyldiphenol based on in situ template mechanism Then the PZS nanotubes were directly used as scafford to load metal Au Ag and Pd nanoparticles respectively through cation complexation followed by gentle reduction The structure and morphology of the metal/PZS nanocomposites were determined by means of Fourier transform infrared spectra energy dispersive Xray spectroscopy elemental analysis Xray diffraction scanning electron microscope transmission electron microscope and thermogravimetric analysis TGA Results showed that the metal/PZS nanocomposites possessed 460 °C of initial thermal decomposition temperature under air atmosphere and the loading amount of metal nanoparticles on the PZS nanotube surfaces could be controlled easily Asfabricated metal/PZS nanocomposites are expected to have potential applications in catalysisThis study was supported by the National Natural Science Foundation of China No 51003098 20974102 20804040 the National Science Foundation for Postdoctoral Scientists of China No 20100480055 201104372 and the financial support from the Program for New Century Excellent Talents in Universities NCET
