摘要

通过溶胶凝胶法，经多次涂覆在SBA-15上负载掺杂镍的纳米TiO2，得到SBA-15/NiO/TiO2复合物；再以TiO2中还原态金属镍为催化剂，通过化学气相沉积法（CVD），在SBA-15/NiO/TiO2表面原位生长碳纳米管，制得SBA-15/Ni/TiO2/CNTs复合材料。通过XRD、SEM、TEM、UV-Vis和Raman等方法考察了SBA-15/Ni/TiO2/CNTs复合材料的结构和性能，并通过降解亚甲基蓝溶液评价其光催化活性。结果表明，SBA-15/Ni/TiO2/CNTs复合光催化剂的催化活性较SBA-15/NiO/TiO2显著提高。二次涂覆掺杂镍的二氧化钛制得的复合光催化剂的催化活性高于一次涂覆。

Abstract

SBA-15/NiO/TiO2 nanocomposites were prepared by coating nano-TiO2 doped with nickel on SBA-15 support using the sol-gel method. Then carbon nanotubes (CNTs) were grown by in-situ chemical vapor deposition (CVD) on the surface of the SBA-15/NiO/TiO2 with metallic nickel reduced in TiO2 as catalyst. The prepared SBA-15/Ni/TiO2/CNTs nanocomposite photocatalysts were characterized by X-ray diffraction

field emission scanning electron microscopy

transmission electron microscopy

UV-Vis absorption spectroscope and Raman spectra. The photocatalytic activities of the samples were investigated by the photocatalytic degradation of methylene blue. The photocatalytic activities of SBA-15/Ni/TiO2/CNTs increased significantly in comparison with SBA-15/NiO/TiO2. The photocatalytic activities of the nanocomposite by twice coating with TiO2 doped with nickel on SBA-15 was also higher than once coating.
