Abstract: In this review, the recent achievements in the synthesis of TiO₂ nanomaterials (particles, tubes, wires, thin films, film electrolyte and porous fibers) as well as their applications in photo-catalysis are presented. The advantages and shortcomings of each synthesis techniques covering microemulsions, templating, sol-gel, VCD and LCD methods are compared with each other. Finally, the further research work is suggested.
