(124b) Synthesis of Graphene Based Iron-Copper Nano-Composites and Its Application in Removal of Methylene Blue

Herein, we report the in-situ synthesis of FeCu nanoparticles with varying concentration on the reduced graphene oxide using NaBH₄ as a reducing agent. The bimetallic-reduced graphene oxide nanocomposite (rGO-FeCu) is characterized by transmission electron microscopy (TEM), and X-ray diffraction (XRD). TEM revealed that average 6nm particles were decorated on graphene sheet. To the best of our knowledge, this is the first report on FeCu bimetallic decorated on the rGO in the degradation of methylene blue (MB) dye. The system of rGO-FeCu and per-carbonate (PC) was used for degradation of dye, which is a highly toxic contaminant in water. The removal of dye was investigated by using rGO-FeCu in the absence and presence of PC. Furthermore, PC concentration, catalyst loading, and dye concentration were systematically studied to understand their effects on the degradation of MB.
