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Ba(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和,得到淡黄色沉淀的Ba4[Ce(Ⅳ)W10 O33]·24H2O纳米粒子.经电镜分析所得Ba4[Ce(Ⅳ)W10 O33]·24H2O纳米粒子为粒径6nm的圆球状颗粒.并用TG—DTA和Raman对该化合物进行了表征.
The nanoparticle Ba4 [Ce ( Ⅳ )W10O33 ] · 24H2O is prepared by replacing component water with 0.1 M Ks [Ce(Ⅳ) ·W10O33 ] · 32H2O and BaNO3 aqueous solution in the TritonX-100/n-C10 H21 OH/H2O W/O microemusion, The nanoparticle is characterized by a combination of transmission electron microscopy ( TEM), TG-DTA and Raman spectra. The average size of the nanoparticles is about 6 nm.
