Fabrication of nZVI/rGO via an innovative thermal co-reduction method for enhanced PFAS removal through sequential adsorption and photocatalytic degradation.

This study investigates the synthesis, characterization, and performance of nanoscale zero-valent iron/reduced graphene oxide (nZVI/rGO) nanohybrids for the efficient removal of per- and polyfluoroalkyl substances (PFAS). The magnetic nanohybrids were fabricated using an innovative thermal co-reduction method, enabling scalable production under inert conditions. Comprehensive characterization confirmed successful integration of nZVI onto rGO sheets, and nanohybrids exhibited high surface area, strong magnetic properties, and effective adsorption and photocatalytic degradation capabilities for PFAS.
