In summary, activated carbon fibers (ACFs) constitute a promising
support material of Fenton-type catalysts for water purification
by means of adsorption and oxidation processes. The combination
of pollutants adsorptive enrichment and catalytic oxidation can
significantly promote the removal of organic pollutants from aqueous
solutions, and the higher adsorption capacities of the support
promote more efficient catalytic performance. This may lead to
improvements in Fenton-type catalytic efficiency via control of
the adsorption capacity of the support material. Furthermore, the
use of H
2
O
in conjunction with Fe@ACFs for dye degradation is
improved in the presence of a high concentration of pollutants
and low concentration of H
2
2
O
. The present study might not only
pave a new avenue for constructing the adsorbent-based Fenton
catalyst with improved catalytic activity, but also provide a preferable
practical approach to treating industrial wastewater pollution.
