采用简单实用的光还原工艺，通过不同的光还原时间，制备了一系列三维微米花状Ag/Bi 2 WO 6复合材料。紫外-可见漫反射光谱表明，Ag/Bi 2 WO 6微球在可见光区的光谱较纯Bi 2 WO 6微球明显红移。以罗丹明B为目标染料，在可见光照射下考察了样品的光催化活性。光还原时间为20 min时，Ag/Bi 2 WO 6的光催化反应速率常数是纯Bi 2 WO 6的3.60倍。光催化活性的提高是由于Ag纳米粒子增加了光吸收范围和有效分离光生载流子的协同作用。
A series of three-dimensional microflower-like Ag/Bi2WO6 composites were synthesized through a simple and practical photoreduction process with different photoreduction times. The UV-visible diffuse reflectance spectra indicate that the spectrum of Ag/Bi2WO6 is significantly red-shifted compared to pure Bi2WO6 microspheres in the visible light region. The photocatalytic activities of the as-prepared samples were evaluated by the decolorization of rhodamine B under visible light irradiation. The photocatalytic reaction rate constants of the Ag/Bi2WO6 with a photoreduction time of 20 min was 3.60 times bigger than those of pure Bi2WO6. The enhanced photocatalytic activity could be attributed to the synergistic effect of increased light absorption range and the effective separation of photogenerated carriers caused by Ag nanoparticles.
