【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。
[Abstract]:With activated carbon as carrier to prepare Ce doped Sn compounds supported particle electrodes by dipping calcination method, the effects of catalyst, Sn-Ce molar ratio and calcination method on the properties of particle electrode. The results show that when the load of active components of catalyst, the molar ratio of Sn-Ce was 3, 2, 400 in C roasting 4 h particle electrodes optimum. Using methyl orange dye wastewater was studied on the electrocatalytic properties of the supported particle electrodes, compared the three-dimensional 3D load load particle electrode, particle electrode, the results showed that the electrocatalytic properties of the electrode, two-dimensional, three-dimensional supported particle electrodes in the initial concentration of methyl orange 50 mg/L and sodium sulfate dosage is 15 g/L, the cell voltage is 12 V under the condition of 40 min of electrolysis, the removal rate of methyl orange can obviously improve the particle loading electrocatalytic electrode reaches 86%.Ce-Sn catalyst Performance.
