| 摘 要： | 通过简单的快速加热回流本体氮化碳制备了缺陷较少的g-C3N4纳米棒；然后采用缓慢水解法在g-C3N4纳米棒表面负载掺杂镍的TiO2前驱体，经热处理制得g-C3N4纳米棒/TiO2/NiO纳米复合光催化剂；最后以TiO2中的Ni为催化剂，采用化学气相沉积法原位生长CNTs，制备g-C3N4纳米棒/TiO2/Ni/CNTs纳米复合光催化剂。通过XRD、TG、TEM、FT-IR、UV-Vis等测试方法对催化剂进行表征，考察了样品在紫外光和可见光下对亚甲基蓝（MB）的光催化降解活性。结果表明：g-C3N4纳米棒/TiO2/Ni/CNT纳米复合物在紫外和可见光下对亚甲基蓝的降解率分别为87%和68%，光催化活性较g-C3N4/TiO2/NiO有明显提高。

| Abstract: | g-C3N4 nanorods with less defects were prepared by rapid heating reflux.The precursor of TiO2 doped with nickel was loaded on the surface of g-C3N4 nanorods,and the g-C3N4 nanorod/TiO2/NiO nanocomposites as photo-catalysts were prepared by heat treatment.Finally,carbon nanotubes (CNTs) were grown on the surface of the g-C3N4 nanorod/TiO2/NiO by in-situ chemical vapor deposition (CVD),using the metal nickel reduced in TiO2 as catalyst.The prepared g-C3N4 nanorod/Ni/TiO2/CNTs nanocomposite photocatalysts were characterized by X-ray diffraction(XRD),thermogravimetry(TG),transmission electron microscopy(TEM),FT-IR and UV-Vis absorption spectroscope.The photocatalytic activities were investigated by the degradation of methylene blue(MB) under UV and visible light,respectively.The degradation rate of MB catalyzed by g-C3N4 nanorod/TiO2/Ni/CNTs nanocomposites were 87% and 68% under UV and visible lights,respectively.The catalytic activity of g-C3N4 nanorod/TiO2/Ni/CNTs was significantly improved compared to g-C3N4/TiO2/NiO. |
