Structural study of titanium dioxide (TiO2) nanopowder prepared by sol-gel under hypercritical drying

Nano-sized TiO2 powders have been prepared by the sol–gel method under hypercritical conditions by hydrolyzing titanium tetra-isopropoxide. The polycrystalline structure and morphology of the powder have been characterized by X-ray diffraction (XRD), Fourier Transform...
