摘 要:采用水热法用钛白粉制备纳米材料,采用浸渍还原法进行Cu2O/TiO2纳米材料的合成。通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)等表征手段对Cu2O/TiO2纳米材料进行分析。探究纳米TiO2和复合材料对农药乙酰甲胺磷的降解效果,结果表明:Cu2O附着在TiO2的表面合成的光催化剂对农药的降解率在210 min内可达80%以上。36917 毕业论文关键词:Cu2O/TiO2;水热法;浸渍还原法;乙酰甲胺磷。
Research on the Synthesis of Cu2O / TiO2 Nanomaterial
Abstract: The hydrothermal synthesis was used to prepare the nanotubes material.The Cu2O/TiO2 nanocomposites have been obtained by impregnation reduction method. The Cu2O/TiO2 nanocomposites was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) for analysising.We explored the degradation effect of nano-TiO2 and composite material on acephate. The results showed that when Cu2O is adhered to the surface of the synthetic material, the degradation rates of TiO2 photocatalytic on pesticides can be up to 80% within 210 min.
Key words: Cu2O/TiO2; Hydrothermal method; Impregnation reduction method; Acephate.
