摘要

光催化剂的回收利用是降低成本的必要条件。然而，大多数重复使用的光催化剂的光催化性能随着循环次数的增加而恶化。因此，确定影响回收光催化剂光催化性能的主导因素，寻找提高回收光催化剂光催化性能的途径势在必行。本文采用溶胶-凝胶法制备了掺杂碳的锐钛矿钛(C-TiO)包封微磁性Fe O粉末，形成了核(Fe O)-壳(C-TiO)结构2

Improvement in Recycling Times and Photodegradation Efficiency of Core-Shell Structured Fe3O4@C-TiO2 Composites by pH Adjustment

Recycling of photocatalysts is necessary for cost reduction. However, the photocatalytic properties of most reused photocatalysts deteriorate with recycled times. Thus, it is imperative to determine the dominant factor that affects the photocatalytic properties of recycled photocatalysts and ﬁnd a way to improve the photocatalytic properties of recycled photocatalysts. In this work, microsized magnetic Fe O powders were 3 4 successfully encapsulated by carbon-doped anatase titanium (C-TiO ) by the sol-gel method to form a core (Fe O )-shell (C-TiO ) structure 2
