In this work, the ZIF-67 derived nitrogen-doped porous carbon/reduced graphene oxide (ZIF-67@rGO) was prepared via hydrothermal method and thermal annealing. ZIF-67 can be converted to porous N-doped carbon with a high Nitrogen content. Graphene oxide among the carbon materials such as graphite, graphene, Vulcan XC-72, Carbon nanotube has been received much interest and attention as catalytic support because of their thermal and electrical conductivities and chemical stability, good mechanical strength. The Pt-ZIF67@rGO was showed that the Pt-ZIF67@rGO is better than Pt/rGO in terms of electrocatalytic activity in fuel cells. The characterization of Pt-ZIF67@rGO composites were measured by cyclic voltammetry (CV), field emission scanning electron microscopy (FE-SEM), Chronoamperometry, fourier transform infrared spectroscopy (FT-IR), transmission electron microscope (TEM). |
