TiO_2 photocatalysts compounded with WO_3 were prepared via a modified hydrolysis process and the 2% WO_3-TiO_2 catalysts with different oxygen vacancies were obtained by calcination at 873 K in H_2 atmosphere.The catalysts were identified using X-ray diffractometry (XRD),specific surface measurement (BET),electron paramagnetic resonance spectroscopy (EPR),UV-Vis diffusion refraction spectroscopy (DRS),and X-ray photoelectron spectroscopy (XPS).The photocatalytic activity of 2% WO_3-TiO_2 with different oxygen vacancies was investigated employi...

与 WO3 加重的 TiO2 光催化剂经由一个修改水解作用过程被准备，有不同的氧空缺的 2% WO3-TiO2 催化剂被锻烧在 H2 空气在 873 K 获得。催化剂用 X 光检查 diffractometry (XRD ) 被识别，特定的表面测量(赌注) ，电子顺磁的回声光谱学(EPR ) ，紫外力的散开折射光谱学(医生) ，和 X 光检查光电子光谱学(XPS ) 。有不同的氧空缺的 2% WO3-TiO2 的 photocatalytic 活动被调查采用为 O2 进化水切开。结果显示适当的氧空缺能显然改进 2% WO3-TiO2 催化剂的 photocatalytic 活动，并且在 12 h 在紫外照耀下面把 Fe3+ 用作一个电子领受人，为 O2 进化的最大的率是 667 mol/(L ? 潰獳獥楳湯吗？
