| Abstract Scope |
This talk presents the synthesis, characterization, and improvement of nitrogen-doped graphene-based catalysts for advanced electrochemical energy conversion and storage systems. The key motivation for this research is replacing or supplementing the cost-ineffective platinum group of metal (PGM)-based catalysts that are commonly used today. We synthesized a Nitrogen-doped Graphene (N-G) catalyst by a high-impact nano wet ball (HI-NWB) milling process which showed electrochemical catalytic performance similar to the standard 10 wt% Pt/C catalyst. Later, this N-G catalyst was integrated with a metal-organic framework material (MOF) to synthesize N-G/MOF catalyst. By this approach we took the advantage of MOF’s structural feature; the high surface area of MOF can host a much higher number of catalytic active sites on the material. The N-G/MOF catalyst showed better catalytic performance than the 10 wt% Pt/C with the same loading in terms of obtained current densities from the electrochemical oxygen reduction reaction. |
