Titanium dioxide (TiO2) is a mesoporous materials having pore size diameter 2-50 nm, pore structure uniform,large surface area, and uniform of pore size distribution. The purpose of this research is to synthesize TiO2 mesoporousmaterials using hydrothermal method, titanium tetra isopropoxide (TTIP) as a precursor and pluronik 123 (P123) assurfactant agent for the pore-forming template. The products of TiO2 mesoporous has analyzed using the Brunauer-Emmet-Teller (BET) methode, FTIR, XRD and DSC. The results of these analyses of surface area and pore sizedistribution were 121 m2/g, pore volume 0.173 cc/g and pore diameter of 9.46 nm. The results of XRD analysis show thetetragonal structure and anatase phase. TiO2 mesoporous was generated the amount of Cu(II) adsorption were 450 mg/gfor 60 minutes and the amount of methylene blue adsorption were 96 mg/g for 60 minutes.
