Synthesis of SO_4~(2-)/Fe_2O_3/ZrO_2 and Catalytic Degradation of Dye Performance

The different proportion of synthesized SO2-4/Fe2O3/ZrO2 catalyst was studied to degrade Rhodamine B.The experiment indicated that SO2-4/Fe2O3-ZrO2 displayed the highest activity for the catalytic degradation of Rhodamine B,which was synthesized by calcination at 600 ℃ of the immersion of 0.5 mol/L and 1.5 mol/L H2SO4 of Fe2O3/ZrO2(Fe:Zr=1:1).The degradation rate of rhodamine B was 90% though the catalyst was repeated three times for 14 h.
