摘　　要：制备了一种高比表面积的CoMn-MOF@NF磁性电极材料,并将之高温碳化获得MnxCoyOz/C@NF多孔骨架材料电极。对比研究了外加磁场对泡沫镍、氧化泡沫镍、碳钢、304不锈钢以及MnxCoyOz/C@NF作为阳极使用降解甲基橙模拟印染废水的影响。研究表明:200 mT恒定外加磁场对无磁性304不锈钢和弱磁性氧化泡沫镍材料的电催化降解效率几乎无正向促进效果,但提高了顺磁性的泡沫镍材料和铁磁性碳钢材料的电催化降解效率,而MnxCoyOz/C@NF磁性电极材料的电催化效率受外加磁场的影响最大,催化降解效率提高了30.97%。A kind of CoMn-MOF@NF magnetic electrode material with high specific surface area was prepared and carbonized at high temperature to prepare MnxCoyOz/C@NF porous skeleton electrode. The effects of magnetic field on the degradation of methyl orange wastewater using nickel foam, nickel oxide foam, carbon steel, 304 stainless steel and MnxCoyOz/C@NF as anode were studied. The results show that the electrocatalytic degradation efficiency of non-magnetic 304 stainless steel and weakly magnetic oxidized nickel foams can hardly be pro-moted by 200 mT constant external magnetic field. However, the electro-catalytic degradation effi-ciency of paramagnetic nickel foam and ferromagnetic carbon steel was improved, and the electrocatalytic efficiency of MnxCoyOz/C@NF magnetic electrode material was most affected by the applied magnetic field, the catalytic degradation efficiency was increased by 30.97%.
