Cu_2O/Cu/SiO_2纳米复合物的制备及光催化性质研究

Synthesis And Photocatalytic Properties Of Cu_2O/Cu/SiO_2 Nanocomposite

采用正硅酸乙酯和硫酸铜为原料,通过Sol-gel法制备了Cu2O/Cu/SiO2纳米复合物。研究了反应中各种因素对产物的影响,确定了最佳反应条件。利用SEM、XRD、EDX、UV-vis、FT-IR、PL等对产物进行了表征。光催化分解有机物实验证明所得产物具有较好的光催化活性。

By a novel sol-gel process,the Cu2O/Cu/SiO2 nanocomposites were synthesized with tetraethyl orthosilicate（TEOS） and Copper sulfate（CuSO4）.The products as-obtained were characterized by a series of means,including Scanning Electron Microscopy（SEM）,X-ray Diffraction（XRD）,Energy-dispersive X-ray analysis（EDX）,Ultraviolet-visible Spectroscopy（UV-vis）,Fourier Transform Infrared（FT-IR） and Photoluminescence（PL）.In addition,the photocatalytic properties of the Cu2O/Cu/SiO2 nanocomposites were studied.
