摘要

本研究采用共沉淀法和水热法制备了0.2CoFe2O4/0.8TiO2-5%La纳米复合材料，并将其作为可见光下降解亚甲基蓝的高活性光催化剂。对0.2CoFe2O4/0.8TiO2-5%La材料进行了x射线衍射、拉曼光谱、扫描电镜/透射电镜和紫外可见光谱等表征。通过亚甲基蓝的分解初步考察了该材料的光催化活性。合成的0.2 CoFe2O4/0.8 TiO2-5% La在可见光照射下对亚甲基蓝具有良好的光催化降解活性。亚甲基蓝在50 min后降解率可达99.14%以上。

Synthesis and photocatalytic activity of a lanthanum doped CoFe2O4/TiO2 nanocomposite for photodegradation of methylene blue organic dye

In this study, a 0.2CoFe2O4/0.8TiO2-5%La nanocomposite was synthesized by a co-precipitation and a hydrothermal method and then was applied as a high activity photocatalyst for degradation of methylene blue under visible light irradiation. The 0.2CoFe2O4/0.8TiO2-5%La material was characterized by X-ray diffraction, Raman spectra, scanning electron microscope/transmission electron microscope and UV-Vis techniques. The photocatalytic activity of the material was initially investigated through the decomposition of methylene blue. The synthetic 0.2 CoFe2O4/0.8 TiO2-5% La showed excellent photocatalytic activity for degradation of methylene blue under visible light irradiation. Methylene blue could be degraded by more than 99.14% after only 50 min.

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
