摘　　要：采用浸渍法研制了Cu O-Ce O2/γ-Al2O3负载型粒子电极,通过扫描电镜(SEM)对粒子电极微观机构、形貌进行表征,将Cu O-Ce O2/γ-Al2O3负载型粒子电极与活性炭填充于电解槽中,考察催化剂强化电化学降解活性艳橙X-GN染料的效果,通过实验确定适宜反应条件。结果表明,Cu O-Ce O2/γ-Al2O3表面晶型明显且结构牢固,具有较大的比表面积和粗糙度;槽电压15 V,初始p H为3.83,支持电解质Na2SO4的质量浓度为16 g/L,曝气体积流量为40 L/h,在此条件下,脱色率可达99.0%以上。采用紫外-可见光谱对反应中间产物进行定性分析显示,以Cu O-Ce O2/γ-Al2O3负载型三维粒子电极降解水中活性艳橙X-GN具有很好的脱色效果。Supported particle electrode Cu O-Ce O2/γ-Al2O3 was prepared by solution impregnation and its microcosmic structure and feature were characterized by SEM. The electro-chemical degradation of reactive brilliant orange X-GN was investigated in the presence of Cu O-Ce O2/γ-Al2O3 and activated carbon as packing materials in the reactor, and the operating conditions were ensured through experiments. Experimental results showed that Cu O-Ce O2/γ-Al2O3 showed clear crystal on the surface with a large specific surface area and roughness and firm structure; cell voltage was 15.0 V, initial p H was 3.83, mass concentration of supporting electrolyte Na2SO4 was 16 g/L, air volume flow was 40 L/h. And in this condition, decolorization ratio can be above 99.0%. The interim product was analyzed by means of Vis-UV absorption spectrum. It showed that color of reactive brilliant orange X-GN was well degraded by supported three-dimension particle electrode Cu O-Ce O2/γ-Al2O3.
