Abstract:
Microbial fuel cells (MFCs) are a green and efficient approach to treat
wastewater and generate energy. According to the present research,
a novel MFC fabricate based on graphite rod electrodes (GRE). The
surface of this cathode was modified with iron-functionalized ZSM-
۵ nanozeolite. The characterization of Iron doping in nanozeolite
structure and electrode surface modification were obtained by XRD
and EDX analyzes, respectively. Chemical analysis of square wave
(Sqw) and cyclic voltammetry (CV) determined for all of three graphite
electrodes (G, G-Z and G-Z/Fe) with higher efficiency. Morover, the
comparison of experimental results from ۷۲-hour fuel cell steering
was evaluated and showed that the G-Z/Fe graphite electrodes has
maximum efficiency and effectiveness. Thus, the efficiency of fuel
cell output current and residual chemical oxygen demand removal
with this electrode increased up to ۲۱.۸% and ۳۶.۹%, respectively.
The effiucient recovery for the modification of the graphite electrode
surface was achieved due to increasing of the specific surface area,
the active sites of functionalized nanozeolite and the elevation in the
electrical conductivity through the presence of iron particles doped in
the ZSM-۵/Fe nanocatalyst structure. Therefore, the G-Z/Fe cathode
can be used as a favorite electrode for the construction of MFCs based
on GRE with high efficiency and economic.
