以Triton X-100/n-C10H21OH/H2O体系W/O微乳液为基础,分别以K8[Ce(Ⅳ)W10O33]·32H2O 和Pb(NO3)2水溶液代替组分水制备W/O微乳液.然后将两种微乳液混合,得到黄色沉淀的Pb4[Ce(Ⅳ)W10O33]·32H2O纳米粒子,同时有少量纳米管生成.经电镜分析所得Pb4[Ce(Ⅳ)W10O33]·32H2O纳米粒子为粒径低于5 nm的圆球状颗粒,所得Pb4[Ce(Ⅳ)W10O33]·32H2O纳米管管长约为50 nm,管径约为5 nm.并用TG-DTA和Raman对该化合物进行了表征.

Nanoparticles and nanotubes of Pb_4\[Ce(Ⅳ)W_(10)O_(33)\]·32H_2O were prepared by replacing component water with 0.01 mol·mL~(-1) K_(8)\[Ce(Ⅳ)W_(10)O_(33)\]·32H_2O and Pb(NO_3)_2 aqueous solution in the Triton X-100/n-C_(10)H_(21)OH/H_2O W/O microemulsion. The nanoparticle was characterized by a combination of transmission electron microscopy(TEM), TG-DTA and Raman spectra. The average size of the nanoparticles was about 5 nm.The length of ...
