Study On The Preparation Of Titanium Dioxide Nanomaterials By Microemulsion And Hydrothermal Synthesis

Titanium dioxide is an important inorganic material,and it has been paid close attention to distinct properties in physics and chemistry.Different morphologies of titanium dioxide nonaparticles were synthesized by microemulsion method and hydrothermal method,respectively.And products were characterized by TEM,XRD and IR.The paper consists of two parts:1.Spherical,flower-like,truss-like and star-like Rutile nanoparticles were synthesized at relatively low temperature in cetyltrimethyl ammonium bromide(CTAB)/n-hexanol/water microemulsion with TiCl₄ as raw material.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.The products were characterized by TEM,XRD and IR.2.TiO₂(B)nanofibers and titanium dioxide nanobelt were synthesized by hydrothermal method with titanium tetrachloride and ethylene glycol.The effects of the time,the reaction temperature,the Molar of reactant,the volume of Ethylene glycol and hydrochloric acid on the morphology of products were studied.And nanomaterials were characterized by TEM,SAED,XRD and IR.
