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.
