摘要：

An organic-inorganic hybrid supramolecular self-assembly was successfully constructed by multivalent interaction of ethylenediamine-beta-cyclodextrin and polyoxometalate in water, which was comprehensively characterized by UV-vis, NMR, Fourier transform infrared spectroscopy, dynamic light scattering, scanning electron microscopy, transmission electron microscopy, Raman spectra, and zeta potential. Interestingly, the resultant nanoparticles exhibited highly efficient catalytic ability for the photodegradation of organic dyes rhodamine B, xylenol orange, methyl orange, methylene blue, and crystal violet, and antibiotics nitrofurazone, tetracyclines, and berberine in the presence of H2O2 under the irradiation of mercury lamp or sunlight, which provides ideas for the treatment of organic pollutants.
