Fe3C-functionalized 3D N-doped carbon structures for electrochemical detection of hydrogen peroxide

Fe3C-functionalized 3D graphite carbon nanocomposite (Fe3C/NG) was prepared by one-pot pyrolysis of FeCl3 impregnated melamine foam. Because of the synergic effect between the two types of active sites from the iron carbide species and the N-doped graphite carbon, the superior electrochemical activity of the advanced Fe3C/NG for hydrogen peroxide detection, as low as 0.035mmol/L of hydrogen peroxide can be detected. The novel and low-cost Fe3C/NG may be a promising alternative in fabricating hydrogen peroxide sensors.
