摘要:

以钛-乙二醇配合物纳米棒为模板, 结合湿浸渍焙烧法制备了不同长度的钛酸镉(CdTiO3)纳米棒. 采用扫描电子显微镜(SEM)、 透射电子显微镜(TEM)、 广角X射线粉末衍射仪(XRD)、 傅里叶变换红外光谱仪(FTIR)、 热重分析仪(TG)及紫外-可见光谱仪(UV-Vis)等对前驱体及CdTiO3纳米棒进行了表征. 结果表明, 得到的CdTiO3纳米棒长度分别约为50, 20和10 μm, 且无杂相, 晶化度高, 尺寸均一. 负载1%(质量分数)铂作为助催化剂后, 制备的不同长度CdTiO3纳米棒具有比CdTiO3纳米粒子更高的光催化产氢活性. 其中, 最长的CdTiO3纳米棒具有最高的产氢活性(~52.9 μmol/h).

Abstract:

CdTiO3 nanorods with different length were prepared from titanium glycolate nanorod template, combined with wet impregnation method and further calcination. The samples were characteried by scanning electron microscope(SEM), transmission electron microscope(TEM), wide-angle X-ray diffractometer(XRD), Fourier transform infrared spectrometer(FTIR), thermogravimetric analyser(TG) and ultraviolet-visible spectrometer(UV-Vis). The prepared CdTiO3 nanorods are uniform with high crystallinity and high purity, and are about 50, 20, 10 μm in length, respectively. After loaded 1%(mass fraction) platinum as co-catalyst, their photocatalytic properties for H2 production were studied. Compared with CdTiO3 nanoparticles, the CdTiO3 nanorods show higher photocatalytic activity. The H2 producton performance for the longest nanorods is up to 52.9 μmol/h.
