摘要
为了降低电芬顿过程中的电能消耗及铁离子浸出量,通过原位还原硫化的方法合成了原位负载在石墨毡(GF)上的高活性电芬顿阴极催化剂Mn-FeS/GF。结果显示,Mn-FeS/GF具有优秀的电催化激活H_(2)O_(2)降解阿特拉津污染物的活性及稳定性,且金属离子浸出浓度较小。Mn元素的引入使得阴极催化剂在低电压下的电芬顿活性显著提高,这对电芬顿过程的实际应用具有重要意义。
In order to reduce the energy consumption and the leaching of iron ions in the electro-Fenton process,a high active cathode of Mn-FeS/GF in-situ loading in graphite felt(GF)was synthesized by insitu reduction and sulphuration.Mn-FeS/GF has excellent activity and stability to activate H_(2)O_(2) for ATZ degradation,and the leaching of metal ions was small.In addition,the introduction of Mn element can result in a significant increase of the electro-Fenton activity at a low potential,which is important for the practical application of the electro-Fenton process.
