Triple layered core–shell ZVI@carbon@polyaniline composite enhanced electron utilization in Cr( vi ) reduction
A triple layered core–shell structured zero valence iron@carbon@polyaniline (ZVI@C@PANI) nanocomposite was synthesized and was used to reduce the Cr( vi ) in wastewater. The synthesized ZVI@C@PANI was demonstrated to have a great Cr( vi ) removal performance with a fast rate and high capacity. ZVI@C...

| description | A triple layered core–shell structured zero valence iron@carbon@polyaniline (ZVI@C@PANI) nanocomposite was synthesized and was used to reduce the Cr(
vi
) in wastewater. The synthesized ZVI@C@PANI was demonstrated to have a great Cr(
vi
) removal performance with a fast rate and high capacity. ZVI@C@PANI can reduce almost all the hexavalent chromium (Cr(
vi
)) (1.0 mg L
−1
) Cr(
vi
) in 5 min, and has a maximum capacity of 508 mg g
−1
. A maximum Cr(
vi
) removal capacity of 508 mg g
−1
was achieved. The shell layers of C@PANI were demonstrated to be important to improve the electron utilization of the inner ZVI. The PANI shell captured and stored the H
+
from the solution, providing an acidic condition on its surface. The carbon layer can adjust the H
+
and H
2
transfer in the ZVI@C@PANI. These were disclosed as the mechanisms for the improved electron utilization by this core–shell structured ZVI@C@PANI. |
