Abstract
AbstractAntibiotic pollution has posed a serious threat to water environments. To cope with this issue, layered double hydroxides (LDHs) have been employed and exhibited effective removability. However, most of LDHs adsorb antibiotics for water decontamination, which is difficult to degrade the pollutants and usually takes a quite long treatment time. In this work, Mn doped NiAl‐LDHs electrode was synthesized for antibiotic degradation with target pollutant tetracycline (TC). The removal efficiency of TC was then investigated by conducting electro‐oxidation with Mn doped NiAl‐LDHs anode. Specifically, some Mn doped NiAl‐LDHs nanoflowers were shed from NF substrate during the oxidation process, thus forming a 3D‐like electrode device and facilitating TC removal. Meanwhile, due to particle electrode‐like architecture and electro‐oxidation of the composite electrode, high concentration of TC can be removed quickly in a short time, and the removal efficiency can reach 92.6% in 5 min.
