Abstract: A series of layered CuyFe6-yAl2Ox catalysts were prepared via the controlled calcination of CuyFe6-yAl2-LDH and applied in the Fenton degradation reaction of high concentrated rhodamine B (RhB, 450 mg·L-1) under neutral conditions at room temperature. It was found that Cu5FeAl2Ox-500, which was prepared at a calcination temperature of 500℃, was most active for the degradation RhB. Over Cu5FeAl2Ox-500 catalyst (with 0.1%(w/w) loading), RhB could be completely degraded within 150 min, and the chemical oxygen demand (COD) removal efficiency reached 86.5%. The characterizations indicated that both Cu and Fe have a good synergistic effect for the degradation reaction as the formation of CuFe2O4. At the same time, the catalyst with larger specific surface area and bigger pore volume was also favorable for the degradation of RhB and COD removal. It was also confirmed that Cu5FeAl2Ox-500 catalyst was capable for the degradation of a variety of pollutants.
