摘要

Mesoporous TiO2 with the visible-light active photocatalyst activity in methylene blue adsorption and Cu(II)ions were effectively synthesized using PVA as a surfactant template through hydrothermal treatment.The preparation of mesoporous TiO2 was identified by X-ray diffraction(XRD),nitrogen adsorption,and scanning electron microscopy(SEM)with EDX.The results nitrogen adsorption on TiO2 indicate the presence of mesoporous materials type IV with H2-type hysteresis loop with specific surface area 106 m~2/g,pore volume 0.18 cc/g,and pore diameter 11 nm.XRD analysis was obtained anatase phase with tetragonal structure.It was observed that the SEM morphology indicated of mesoporous TiO2 were successful.In addition,the performance of a photocatalytic activity in methylene blue and Cu(II)ions physisorption as a model organic and inorganic pollutants was 96 mg/g and 1620 mg/g.The findings of this study suggest that it is surprising to clear the environment by degradation treatment of wastewater.
