摘要 采用阳极氧化法制备得到TiO2纳米管阵列(TiO2-NTA),同时借助光化学还原法将纳米Ag颗粒沉积于TiO2-NTA表面(Ag/TiO2-NTA)。利用X射线衍射(XRD)、紫外-可见吸收光谱(UV-vis)、扫描电镜(SEM)对样品的晶型、光响应性能、表面形貌等进行了表征。分析结果表明,TiO2-NTA管径约为150nm,壁厚约为20nm,纳米Ag颗粒以单质形态分散于TiO2-NTA表面,其等离子体效应可以有效促进TiO2-NTA对可见光的吸收,共振吸收波长位于420nm。光解水制氢实验结果表明,Ag/TiO2-NTA的光催化活性高于纯的TiO2-NTA,前者约为后者的2.3倍。 采用阳极氧化法制备得到TiO2纳米管阵列(TiO2-NTA),同时借助光化学还原法将纳米Ag颗粒沉积于TiO2-NTA表面(Ag/TiO2-NTA)。利用X射线衍射(XRD)、紫外-可见吸收光谱(UV-vis)、扫描电镜(SEM)对样品的晶型、光响应性能、表面形貌等进行了表征。分析结果表明,TiO2-NTA管径约为150nm,壁厚约为20nm,纳米Ag颗粒以单质形态分散于TiO2-NTA表面,其等离子体效应可以有效促进TiO2-NTA对可见光的吸收,共振吸收波长位于420nm。光解水制氢实验结果表明,Ag/TiO2-NTA的光催化活性高于纯的TiO2-NTA,前者约为后者的2.3倍。
