Abstract
In this work, a three-dimensional bimetallic metal-organic framework (BMOF), BUC-101 (Co/Mn-H6chhc, H6chhc = cis-1,2,3,4,5,6-cyclohexane-hexacarboxylic acid, BUC = Beijing University of Civil Engineering and Architecture) was synthesized by a one-pot solvothermal method and characterized in detail by single crystal X-ray diffraction (SCXRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) element mapping analysis. BUC-101 showed excellent catalytic peroxymonosulfate (PMS) activation performance to degrade rhodamine B (RhB) without energy input. In addition, BUC-101 can maintain good stability and recyclability during the PMS activation processes, in which 99.9% RhB degradation efficiencies could be accomplished in 5 operational runs. The possible PMS activation and RhB degradation mechanisms of the BUC-101/PMS system were proposed and affirmed.
