摘要：

In this study, hierarchical Ag/La2O2CO3 micro/nanostructures (MNSs) were synthesized by in situ loading Ag nanoparticles (NPs) on the surface of the La2O2CO3 MNSs. The prepared La2O2CO3 MNSs present flower-like shape and can be tuned by the molar ratio of La (NO3)(3) and CO(NH2)(2). In the molar ratio of 1:2 to 1:55, the La2O2CO3 MNSs mainly consist of polyhedral rods, irregular rods and irregular spindles and their size is about 10, 8 and 7 mu m, respectively. After loading Ag NPs, the spindle-like Ag/La2O2CO3 MNSs were used for phosphate removal and antibacterial activity. At the initial phosphate concentration of 20 mg/L, the removal rate is 59.6%. The Ag/La2O2CO3 MNSs have significant antibacterial activity and their MIC values for S. aureus and E. coli are 31.3 and 15.6 mu g/mL, respectively. The results indicate that Ag/La2O2CO3 MNSs may have good application prospects in open water to inhibit bacterial growth.
