Pt-based noble metals have been predominantly used as electrocatalysts for energy conversion devices such as fuel cells and solar cells during the last decades. Although Pt-based catalysts are highly efficient in electocatalytic reactions, their high costs and limited supplies have triggered a great deal of recent efforts toward seeking low-cost alternatives for Pt. In this presentation, the prepartion of new electroactive ordered nanoporous carbons, and their applications as non-precious-metal electrocatalysts for cathode of polymer electrolyte membrane fuel cell as well as for counter electrode of dye sensitized solar cell will be presented. |
