摘　　要：以活性炭为载体,采用浸渍焙烧法制备Ce掺杂Sn化合物负载型粒子电极,考察了催化剂活性组分Sn-Ce物质的量比和焙烧方式对粒子电极性能的影响,结果表明,当负载催化剂活性组分Sn-Ce物质的量比为3∶2时,在400℃恒温焙烧4 h的粒子电极电催化性能最优。以甲基橙为模拟染料废水对负载型粒子电极的电催化性能进行了研究,对比了三维负载粒子电极、三维不负载粒子电极、二维电极的电催化性能,结果表明,三维负载粒子电极在甲基橙初始质量浓度为50 mg/L、硫酸钠用量为15 g/L、槽电压为12 V的情况下电解40 min时,甲基橙的去除率达到86%。Ce-Sn催化剂的负载可以明显改善粒子电极的电催化性能。With activated carbon as carrier, the pupported particle electrodes for Ce doped Sn compound were prepared by the method of impregnation roasting. The effect of the mole ratio of Sn and Ce and the way of roasting on the performance of particle electrode was studied. The results showed that the particle elec- trode had the best electrocatalytic performance under the conditions of the mole ratio of Sn and Ce was 3：2, roasting at 400 ℃ for 4 h. Using methyl orange as simulated dye wastewater, the electrocatalytic properties of three-dimensional loaded particle electrode, three-dimensional non-loaded particle electrode, two-dimension- al electrode were studied. The results showed that in the case of three-dimensional loaded particle electrode, when the initial concentration of methyl orange was 50 mg/L, dosage of sodium sulfate was 15 g/L, slot volt- age was 12 V, electrolysis time was 40 min, the removal rate of methyl orange was 86%. The loading of Ce-Sn catalyst could significantly improve the electrocatalytic properties of the particle electrode.
