Ce-Doping Enhanced Catalytic Performance of Cobalt-Based Bimetallic MOFs for Ultrafast Degradation of Rhodamine B via Peroxymonosulfate Activation
In view of the harm of dye wastewater to the ecological environment and human health and the limitations of traditional treatment technologies, this study focused on the advanced persulfate oxidation technology (PS-AOPs), which synthesized cerium-doped cobalt-based bimetallic organic framework materials (Co/Ce-MOFs-NH₂) by solvothermal method for the activation of pyrosulfate (PMS) for the degradation of rhodamine B (RhB). The rare earth element cerium (Ce) was innovatively introduced to construct a bimetallic synergistic system to solve the problems of single active site and poor cycling stability of monometallic Co-MOFs. The effects of catalyst dosage, PMS concentration, initial pollutant concentration and pH value on the degradation efficiency were systematically explored, and the hydroxyl radicals (·OH). This study provides theoretical support for the design of rare earth element enhanced bimetallic MOFs catalysts.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
