ACF/TiO_2复合材料的制备及光催化降解偏二甲肼废水

Preparation of ACF/TiO_2 Composite Material and Photocatalytic Degradation of UDMH Wasterwater

用溶胶-凝胶法制备ACF/TiO2复合材料,并用于光催化降解偏二甲肼废水。同时,还讨论了材料的活化温度、偏二甲肼废水的初始浓度、H2O2及催化剂重复利用等因素对光催化效率的影响。实验结果表明,当材料的活化温度为300℃,体系中H2O2的浓度为0.12mol/L时,偏二甲肼的降解效果良好,偏二甲肼40min后的降解率达到99%以上。

The composite material ofACF/TiO2 which is used as photocatalyst to degrade wastewater of unsymmetrical dimethyl hydrazine（UDMH） was prepared by sol-gel method. Meanwhile, the influence of factors such as the activation temperature of the material, the initial concentration of the wastewater, H2O2 and the reuse of the catalyst on photocatalytic efficiency is discussed. The results show that degradation effect is ideal, the UDMH in the wastewater can be degraded over 99% in 40min when the activation temperature of the material is 300 % and the concentration of H2O2 is 0.12 mol/L.
