Abstract
A simple approach was proposed to synthesize three types of ellipsoidal hollow nanostructures whose shells are assembled from anatase TiO(2) nanosheets (NSs) with exposed (001) facets. Among them, ellipsoid Fe(3)O(4)@TiO(2)-NS nanorattles can be readily generated as a magnetically separable photocatalyst with enhanced activity through in situ reduction of the α-Fe(2)O(3) core.
摘要
提出了一种简单的方法来合成三种类型的椭圆形空心纳米结构，其外壳由暴露（001）面的锐钛矿 TiO(2) 纳米片 (NS) 组装而成。其中，通过α-Fe(2)O(3) 核的原位还原，很容易生成具有增强活性的可分离磁性光催化剂 Fe(3)O(4)@TiO(2)-NS 纳米笼。
