چکیده:

The discovery of mesoporous TiO2 with large surface areas and narrow pore size distribution, obtained by a modified sol-gel method with phosphorus surfactants as templates by Antonelli and Ying, has opened many possibilities for applications in catalysis, separation and nanoscience. In this paper, we report synthesis of nanoporous TiO2 material by a new sol-gel method and we did hydrothermal treatment for its crystallization, which may cause better crystalline structure and higher surface area than previous works. After synthesize we determine the nanoporous material properties by using of technologies such az X-ray powder diffractometry (XRD), Infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermal analyses (TG/DTA) and N2 sorptiometry. Finally, we examined the material as a new adsorbent with adsorption of nickel (II) cations from laboratory water samples
