| 摘 要： | 通过高温固相反应合成了钼掺杂的铌钙酸钾系列,并通过离子交换反应制备出钼掺杂的铌钙酸系列,采用X射线衍射、紫外-可见漫反射光谱、扫描电镜等对所制得的样品进行了表征.在甲醇为电子给体、Pt为助催化剂的情况下,研究了钼掺杂的铌钙酸系列催化剂,在波长＞290nm紫外光辐射下分解水产氢的光催化活性,结果表明钼的掺杂有效地提高了铌钙酸的光催化活性,并讨论了引起催化剂活性差异的原因.

| Abstract: | The photocatalysts series HCa2Nb3O10 doped with Mo6+ were prepared by conventional solid-state reactions followed by an ion-exchange reaction.The samples were characterized by power X-ray diffraction,UV-vis diffusive reflectance spectrum and scan electron microscope.The photocatalytic activities of HCa2Nb3O10 doped with Mo6+ are investigated with methanol as electron donor and Pt as promoter catalyst under irradiation of UV light with wavelength more than 290nm.The results show that the doping of Mo improves the photocatalytic activity of HCa2Nb3O10,the difference of photocatalytic activity among them is also discussed. |
