摘要
采用浸渍-煅烧法制备出SnO_2/石英柱粒子电极,用SEM,XRD,XPS等手段对其进行表征,并以四环素为目标污染物,构建了三维粒子电极体系进行电催化降解,研究粒子电极的电催化活性,优化粒子电极制备条件和电催化反应条件,煅烧温度550℃,煅烧时间5 h为粒子电极的最佳制备条件。在外加电压为15V,极板间距为6cm,粒子电极投加量为32g的条件下,反应120 min,四环素降解率可达到88.6%,比传统二维电极高25.3%,表明粒子电极有较好的电催化活性。
The SnO_2/ quartz column particle electrode was prepared by dipping-calcination method.The samples were characterized by SEM,XRD and XPS.The results indicated that cassiterite SnO_2 was successfully loaded on the quartz column.The electrocatalytic activity of the particle electrode was evaluated by tetracycline degradation.The optimum calcination temperature and calcination time to prepare SnO_2/ quartz column particle electrode were550℃ and 5 h.When the cell voltage was 15 V and the dosage of particle electrode was 32 g,they performed a pretty good electrocatalytic property in tetracycline degradation.88.6% TC was degraded in 2 h and it was 25.3%higher than that in two-dimensional system.The SnO_2/ quartz column particle electrode performed good electrocatalytic activity.
