Abstract

ZnO, NiFe₂O₄, NiFe₂O₄/TA
and NiFe₂O₄/TA/ZnO photocatalyts were successfully
synthesized and characterized, and they demonstrated significant photocatalytic
efficiency under visible-light. The photodegradation rates of congo red (CR)
are 35.7%, 19.4%, 25.5% and 91.1% over the ZnO, NiFe₂O₄,
NiFe₂O₄/TA and NiFe₂O₄/TA/ZnO for
180 min, respectively. The results display that the NiFe₂O₄/TA/ZnO
has the most excellent photocatalytic efficiency for CR among to the other
photocatalysts. Furthermore, NiFe₂O₄/TA/ZnO may be
separated easily from solution by magnet because of the magnetic property of
NiFe₂O₄. The considerable increment in efficiency of NiFe₂O₄/TA/ZnO
can be attributed to synergistic effects between NiFe₂O₄,
the tannic acid (TA) and ZnO, which extend lifetime and hinder the
recombination of photogenerated charge carriers. This work presents new
perspectives on the use of tannic acid based magnetic photocatalysts in
wastewater treatment.
