Enhanced activation of peroxymonosulfate on layered molybdenum disulfide loaded with Co–La bimetallic oxide for efficient degradation of chloramphenicol

引用

Rare Metals 2024年第9期43卷 4628-4635页

作者： Yu-Ning fan Yun-Qiu Zhang San-Shuang Gao Zeng-hui Bi Yin Wang Shu-Xing Zhou Qian Liu Tian-Ping Lv Guang-Zhi Hu Institute for Ecological Research and Pollution Control of Plateau Lakes School of Ecology and Environmental ScienceYunnan University Hubei Key Laboratory of Low Dimensional Optoelectronic Materials and Devices Hubei University of Arts and Science Institute for Advanced Study Chengdu University

The use of transition metal-activated peroxymonosulfate（PMS） as an advanced oxidation technology has gained recognition. This study developed a catalyst using cobaltDlanthanum bimetallic oxide supported on layered molybdenum disulfide （Mo S2） as a carrier. The CoDLa/Mo S2catalyst was synthesised through coprecipitation, followed by calcination with an optimised metal ratio of Co:La=2:1 to activate PMS and degrade trace chloramphenicol（CAP） in water. The chemical composition of the catalyst was confirmed using X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. At catalyst and PMS dosages of 0.1 and 0.5 g·L-1, respectively, the degradation rate of CAP was 95% with in 30 min. The catalyst exhibitedstrong resistance to most interfering anions and maintained a high degradation rate at p H 3D11. Liquid chromatographyDmass spectrometry analysis revealed the potential degradation pathways of CAP in the CoDLa/Mo S2（2:1）/PMS system. For other pollutants, such as oxytetracycline,complete degradation was achieved within 20 min,demonstrating the broad applicability of the CoDLa/Mo S2（2:1）/PMS system for the degradation and removal of antibiotic organic contaminants. This study offers a feasible approach for the degradation of antibiotic organic pollutants, including CAP, in natural water bodies.
