Construction of 3D-sized Mn (II)-doped MoS2@activated alumina beads as PMS activator for tetracycline degradation under light irradiation

In this work, Mn (II) was doped into MoS 2 structure and then anchored on activated alumina beads to construct 3D-sized composites (Mn-MoS 2 @AABs). This component material was used as PMS activator for tetracycline (TC) degradation under light irradiation. According to experiment results, Mn-MoS 2 @AABs exhibited well degradation performance to TC, which ascribed to excellent photo-response property of Mn-MoS 2 and activation of Mn. Importantly, the 3D-sized structure made it facilely be recycled from solution, which catered to the demand for the practical application. Therefore, the novel strategy of designing Mn-MoS 2 @AABs had great significance for environmental restoration.
