复合光催化剂CF-ZnO/g-C3N4的制备及其可见光下光催化活性的增强
|
Abstract:
通过煅烧法制备了不同ZnO含量的CF-ZnO/g-C3N4复合光催化材料，对材料进行了SEM和XDR表征，并建立了CF-ZnO/g-C3N4光催化降解实验体系。实验结果表明，CF-ZnO/g-C3N4在可见光照射下，光催化剂可在80分钟内降解97%的甲基橙。光催化性能的提高可归因于ZnO和g-C3N4之间的协同效应，增强了电荷分离效率。
CF-ZnO/g-C3N4 composite photocatalytic materials with different ZnO contents were prepared by calcination method. The materials were characterized by SEM and XDR, and an experimental system for CF-ZnO/g-C3N4 photocatalytic degradation was established. The experimental results show that under visible light irradiation, CF-ZnO/g-C3N4 photocatalyst can degrade 97% of methyl orange within 80 minutes. The improvement in photocatalytic performance can be attributed to the synergistic effect between ZnO and g-C3N4, which enhances the charge separation efficiency.
