【摘要】 采用低温一步法合成了钨掺杂的二氧化钛,并用X射线衍射(XRD)、红外光谱(IR)、紫外可见漫反射光谱(UV-Vis)等方法对其结构进行了表征。发现掺杂钨的二氧化钛为锐钛矿型晶型,且在可见光区有明显的吸收。以苯酚的光催化氧化降解反应为探针,研究了催化剂的光催化性能。结果表明．本方法合成的钨掺杂的二氧化钛具有理想的可见光催化活性。更多还原

【Abstract】 WOx-TiO2 samples were prepared by low temperature one step process. The construction of the photocatalysts was characterized by XRD,IR,UV-vis absorption spectra. It is discovered that the TiO2 doped with W was anatase and could effectively respond to the visible-light. The photocatalytic activity was investigated with phenol as a photocatalytic degradation modal reactant. The results showed that the photocatalytic activity of TiO2 was perfect after being doped with W by this method.更多还原
