Structural, optical and photoelectrochemical properties of TiO2 films decorated with plasmonic silver nanoparticles

Preparation of SiO2@Ag@SiO2@TiO2 Core-shell Structure and Its Photocatalytic Degradation Property

“…因此，研究者 们采取多种方式对其进行改性，负载改性是最常用 的手段之一. SiO2 是一种理想的负载基底， 具有可变 的禁带宽度、高热稳定性、高机械强度和分散性良 好等优点，它与催化剂的协同作用可有效提升 TiO2 的光催化活性 [15][16][17] . Yu 等 [18] 制备了夹层结构的多孔 Fe2O3@SiO2@TiO2 复合微球，其降解罗丹明 B 染料 分子的光催化活性与 Fe3O4@TiO2 微球相比得到了 显著提高，归因于 SiO2 中间层是染料分子的良好吸 附剂，增强了污染物染料分子在多孔 TiO2 光活性层 周围的富集.…”

Effect of Synthesis Method and Amount of Silver on Physicochemical Properties and Photocatalytic Activity of Ag Doped TiO2 Nanoparticles

“…Silver (Ag) metal doping on TiO 2 has been recommended in many researches [12][13][14] for improving the photoactivity of TiO 2 [5]. Ag deposited on TiO 2 has positive effects on the photoactivity in terms of narrowing band gap energy of TiO 2 by the surface plasmon resonance of Ag, resulting in extend range of the visible light absorption [15] and prevention of recombination between electron-hole pair [10].…”
