In this study, nanoscale
zero-valent iron (nZVI) particles were
synthesized on fullerene, carbon nanotubes, and graphene to use with <i>S. putrefaciens</i> for U(VI) reduction under light conditions.
Of the three composites, the nZVI-carbon nanotube (nZVI-CNT) composites
removed the highest amount of U(VI) of 1210.9 mg/g. The nZVI-CNT composites
and <i>S. putrefaciens</i> exhibited a synergistic effect
on U(VI) reduction under light conditions. X-ray photoelectron spectroscopy
(XPS) and X-ray diffraction (XRD) results revealed the presence of
U(IV) species on the reacted bio-nZVI-CNT. <i>S. putrefaciens</i> might decrease the interfacial energy barrier of the photocatalytic
reduction process in the bio-nZVI-CNT system. This work highlights
the enhanced U(VI) removal capacity of the complex nZVI-CNT and electricigen
hybrid system and provides a promising strategy for wastewater treatment.
