文摘
- •
Ring-opening of BDE209 was realized by the Fe0@Fe3O4 in the reduction-oxidation system.
- •
A two-stage reduction/subsequent oxidation degradation mechanism was proposed.
- •
The reduction ability of nZVI was efficiently supported by Fe3O4 which acted as a catalyst.
- •
OH generated on the composite surface and solution attacked the debromination products.
