摘要

Developing efficient catalysts capable of degrading organic dye free of light irradiation is highly interesting from the energy-saving point of view. In this work, we prepared a new Ce(IO3)(4) catalyst by a facile precipitation method. The obtained Ce(IO3)(4) sample showed remarkably superior performance to the reported CeGeO4 analog in degradation of rhodamine B (RhB), methyl orange (MO) or methylene blue (MB) dyes in the dark at room temperature. The ultraviolet-visible (UV-vis) absorption spectra of dye solution during degradation, the XPS results of Ce(IO3)(4) and the control experiments confirmed that the dye degradation is a catalytic process. The reusability of it was also investigated in the degradation experiments.
