摘要: 以TiCl4为原料、在十六烷基三甲基溴化铵/正己醇/水组成的微乳液体系中、在较低温度下,制备了球形、花状、捆绑丝和星形的金红石型二氧化钛纳米颗粒。研究了w值(水与CTAB物质的量之比)、反应物浓度、反应温度以及P值(正己醇与CTAB的物质的量之比)等因素对产品形貌的影响,并用TEM、XRD对产品进行了表征。 |

Abstract: Spherical, flower-like, truss-like and star-like rutile nanoparticles were synthesized at relatively low temperature in cetyl trimethyl ammonium bromide(CTAB)/n-hexanol/water microemulsion with TiCl4 as raw material. The products were characterized by TEM and XRD. The effects of the water-to-surfactant molar ratio(w), the concentration of reactants, the reaction temperature and the n-hexanol-to-surfactant molar ratio (P) on the morphology of products were studied. |
Keywords: W/O microemulsion rutile nanoparticles |
