| 摘要: |
To minimize the aggregation and size effects of nanoscale zerovalent iron (nZVI), nZVI/boron nitride nanosheets (BNNSs) composites were fabricated via a one pot “autoclave route” on a gram-scale. BNNSs (1–6 nm) supported nZVI (4–40 nm) was prepared by heating NaBH4, FeCl3 and NaN3 at 400 C. The
BNNSs matrixes benefit the retention of the activity for nZVI. The high specific surface area (182 m2 g1) and density of structural defects allows enrichment of the pollutants, leading to a relatively high conversion by the nearby supported nZVI. Meanwhile, the gram-scale bifunctional nZVI/BNNSs have
both reductive and magnetic properties, which make them highly reactive towards the test polybromodiphenyl ethers (PBDEs) and also easy to separate. The reaction rate of nZVI/BNNSs is almost twice that of the nZVI made in our lab. This study indicates that gram-scale nZVI/BNNSs are highly
efficient and effective materials that can be utilized to treat PBDEs-contaminated sites, followed by the sequential magnetic separation. |
