By methyl methacrylate (MMA) and vinyl benzyl chloride (VBC), obtained by solution polymerization in the copolymer of P (MMA-co-VCB), then the copolymers obtained by electrospinning spinning micron fibers. By atom transfer radical polymerization (ATRP) the reaction is carried out in the introduction of the fiber surface trimethoxy silicon group, tetraethoxy silane (TEOS) sol - gel reaction of the surface of the fiber to form a coated SiO 2 < / sub> shell. The fibers are placed 600 ° C, to decompose and remove the internal polymer template obtained the hollow SiO 2 microtubes. The resulting product and intermediate infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) were characterized. The results show that: the trimethoxysilyl groups was successfully introduced into the surface of the fiber to the obtained SiO 2 hollow microtubes shell thickness of about 0.25μm, SiO 2 was an amorphous structure. Γ-Al 2 O 3 nanoparticles as a template, the use of its surface hydroxyl groups with 3 - mercapto-propyl trimethoxy silane (MPTMS) reaction, to obtain the functionalized γ-Al 2 O 3 nanoparticles, palladium nanoparticles by sulfhydryl adsorption, and gradually warming restore the Pd 2 get the metal palladium shell, room temperature etching with 40wt% hydrofluoric acid solution to remove the γ-Al 2 O 3 template, and to obtain a hollow nano-palladium particles. Infrared Spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) results show that the X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET), characterized, hollow palladium nanoparticles shell The layer thickness is about 10nm, and a diameter of about 120nm, a specific surface area of ??76.4 m 2 / g. By soap-free emulsion polymerization, polystyrene-co-methacrylic acid-2 - amino ethyl ester hydrochloride copolymer (P (St-co-AEMH)) nano-latex particles were successfully prepared. Latex particles as a template, the amino group through its surface adsorption of gold sol nanoparticles. Adsorption of gold sol nanoparticles as nucleation sites for seed and reaction with hydroxylamine hydrochloride restore the HAuCl 4 / K 2 the CO 3 solution get P (St-co-AEMH) / Au core / shell nanocomposite particles. Composite nano-particles of the resultant was treated with concentrated sulfuric acid for 10 days, the particles of the polymer template is removed to obtain a hollow gold particles. The structure and morphology of the products by infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermal gravimetric analysis (TGA) were characterized. The results showed that the hollow gold particle diameter of approximately 220nm, the thickness of the gold shell about 30 nm, the covering rate of the surface of the nanoparticles of gold about 75%, more complete and uniform coating of gold shell.
