Synthesis of Titania Microshperes with Controllable Diameter Under Solvothermal Conditions
Abstract:
Bead-structured titanium dioxide microspheres were successfully prepared by a facile one-step solvothermal method using diblock copolymers poly(ethylene oxide)-block-polystyene (PEO-b-PS) as the structure-directing agent. The products were characterized by scanning electron microscopy, thermogravimetic analysis and X-ray powder diffraction (XRD) technique. The XRD patterns show that the products synthesized with low content of HCl are anatase titanium dioxide and the products synthesized with low content of HCl are rulite titanium dioxide.
