摘要:
通过高温固相反应制备铬掺杂的钙铌酸钾系列样品,并用离子交换反应制备出对应的铬掺杂钙铌酸样品.采用X-射线衍射、紫外-可见漫反射光谱、扫描电镜等方法,对所制得的样品进行表征.在甲醇为电子给体,Pt为助催化剂的情况下,研究铬掺杂的钙铌酸系列催化剂,在波长大于290 nm紫外光辐射下分解水产氢的光催化活性.结果表明,适量的掺杂铬可有效地提高钙铌酸的光催化分解水的活性.最后,讨论引起催化剂活性差异的可能原因.
Abstract:
The photocatalysts series HCa2Nb3O10 doped with Cr3+ were prepared by conventional solid-state reactions followed by an ion-exchange reaction.The samples were characterized by powder X-ray diffraction,UV-Vis diffusive reflectance spectrum and scanning electron microscope.The photocatalytic activities of HCa2Nb3O10 doped with Cr3+are investigated with methanol as electron donor and Pt as promoter catalyst under irradiation of UV light with wavelength more than 290 nm.The results show that the doping of Cr3+ improves the photocatalytic activity of HCa2Nb3O10,the difference of photocatalytic activity among them is also discussed.
