Abstract:

Pd/polyelectrolyte hollow nanospheres were prepared by a facile method that combined the surface-initiated atom transfer radical polymerization(SI-ATRP) and in situ growth of metal nanoparticles. Transmission electron microscopy(TEM), Fourier transform infrared spectra(FTIR), energy-dispersive X-ray(EDX) and thermogravimetric analysis(TGA) were used to characterize the morphology and structure of air@PMETAI@Pd(PMETAI:poly{[2-(methacryloyloxy)ethyl] trimethylammonium iodide}) nanospheres. The result shows that Pd nanoparticles with diameter of (1.5±0.2) nm are homogeneously embedded inside the polyelectrolyte layer. Catalytic activity of the Pd/polyelectrolyte hollow nanospheres was investigated by the reduction of 4-nitrophenol with NaBH4 as a model reaction. It is found that they displayed excellent catalytic properties and good reusability.
