A Fe@GE composite has been synthesized by using glucose as the carbon source, NH4Cl as the foaming agent, nano-Fe as the catalyst to promote the graphitization of glucose. The Fe@GE composite exhibits high degree of graphitization with less defects, which is confirmed by UV-Vis and Raman. Using Fe@GE as the substrate material, a 3-D Fe@GE-Cu composite has been fabricated with the incorporation of nano-Cu through low-temperature hydrothermal method, as testified by TEM and FESEM. The Fe@GE-Cu composite is stable under ambient state according to the analysis of XRD, FTIR and ICP. The catalytic reduction activity of the composite has been tested through the reaction of 40 mL K2Cr2O7 solution ( 200 mg/L ), after adding 1 mL (88wt%) HCOOH and 10 mg Fe@GE-Cu0.65 catalyst, 100% of Cr(VI) has been reduced in 9 minutes. It shows the composite has high catalytic activity in the reduction of Cr(VI) and could be applied in solving problems of heavy metal pollution.
