酞菁类复合催化剂对染料橙黄Ⅱ水溶液的光催化脱色研究

Photocatalytic decolorization of Orange Ⅱ solution by combined phthalocyanine catalysts

制备了复合催化剂酞菁蓝 (CuPc) TiO2 、FePz(Cu -Fe) TiO2 、TiO2 α Fe2 O3、TiO2 β FeOOH、酞菁蓝 α Fe2 O3、酞菁蓝 β FeOOH .在紫外灯 (15W ,λmax=2 5 4nm)的照射下 ,通过对照实验 ,研究了复合催化剂对橙黄Ⅱ水溶液的光催化脱色效果 ,初步考查了复合光催化剂投加量。

Six combined catalysts——CuPc TiO 2, FePz(Cu Fe) TiO 2, TiO 2 α Fe 2O 3, TiO 2 β FeOOH, CuPc α Fe 2O 3, and CuPc β FeOOH were prepared. Their properties of photocatalytic decolorization of Orange II solutions were investigated under the irradiation with UV lamp(15W, λ max =254nm). Effects of pH and dosage of catalysts on the decolorization efficiency were studied.
