合成了不同比例的硫酸根/氧化铁-氧化锆催化剂,并研究了它们催化降解罗丹明B的性能。考察了不同条件下合成的催化剂对罗丹明B的影响。实验表明:当反应温度为40℃,10 mg硫酸根/氧化铁-氧化锆作催化剂和0.91 mol/L H2O2作氧化剂催化降解100 mL 20 mg/L的罗丹明B溶液,在n(Fe)∶n(Zr)=1∶1,浸泡所用硫酸的浓度分别为0.5 mol/L和1.5 mol/L,煅烧温度为600℃等条件下合成的催化剂的活性最高,对罗丹明B的催化降解速率最大。在将该催化剂连续催化降解14h,此过程重复循环反应3次,罗丹明B的降解率都能够达到90%。该催化剂在染料降解方面具有较大的应用前景和研究价值。

This paper studies synthesis of the different proportion of SO42-/Fe2O3-ZrO2 catalyst,and the catalytic degradation of performance with Rhodamine B.It is important to inspect the different experimental conditions(different proportions of Fe and Zr,the concentration of different H2SO4 for immersion,different temperature).Synthesis of catalyst to affect of photocatalytic degradation of Rhodamine B.The results indicate when the reaction temperature is 40℃,10 mg SO4^2-/Fe2O^3-ZrO2 as catalyst and 0.91 mol/L H2O2 as oxidants to photocatalyst degradation of 100 mL 20 mg/L Rhodamine B.When the nFe∶nZr=1∶1,sulfuric acid used in immersion concentrations were 0.5 mol/L and 1.5 mol/L,calcination temperature of 600 ℃ to give out catalyst with the highest activity for catalytic degradation of Rhodamine B and the greatest rate.Catalyst in the catalytic degradation for 14 h,repeated cycle of reactions for three times,the degradation rate of rhodamine can be 90%.It can be seen that the catalyst has a larger value of application and research prospects in degradation of the dye.
