Nano zero-valent iron, as an electron donor, transferred electrons to pentabromodiphenyl ether molecules during ball-milling. The C-Br bond was stretched, and the bond length increased, which promoted the debromination process. We also found that in the pentabromodiphenyl ether molecule, the C-Br bond in the para position on the benzene ring with more Br atoms and the C-O bonds were …
