借助棉花纤维模板、利用两步法制备了Ti4+/ZnO多壁纳米纤维结构材料,利用热重分析(TG)、X射线衍射(XRD)和扫描电子显微镜(SEM)等技术手段对其进行了表征;以亚甲基蓝(MB)的降解脱色为模型反应,考察了Ti4掺杂量对ZnO多壁纳米纤维结构材料光催化性能的影响.结果表明,利用模板辅助的两步法成功制备了Ti4掺杂的ZnO多壁纳米纤维结构材料(Ti4 +/ZnO);Ti4+的掺入影响ZnO材料的纳米结构,从而使Ti4+/ZnO的光催化性能明显高于ZnO;Ti4+/ZnO多壁纳米纤维结构材料良好的光催化性能可主要归于Ti4+/ZnO材料中活性中心-O2--Ti4-O2--Zn2+-的形成和光生电荷e--h+沿着颗粒间的有效传递.
