  • Abstract
  • Replacement of precious metal catalysts by commercially available alternatives is of great importance among both fundamental and practical catalysis research. Nanostructured carbon-based and transition metal materials have demonstrated promising catalytic properties in a wide range of energy generation/storage applications. Specifically engineering carbon with guest metals/metal-free atoms can improve its catalytic activity for electrochemical oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), thus can be considered as potential substitutes for the expensive Pt/C or IrO2 catalysts in fuel cells, metal-air batteries and water splitting process. In this presentation, we will talk about the synthesis of nonprecious metal and metal free elements-doped carbon, and their application on electrocatalysis [1-8]. The excellent ORR, OER and HER performance (high catalytic activity and efficiency) and reliable stability (much better than the commercial Pt/C or IrO2) indicate that new materials are promising highly efficient electrocatalysts for clean energy conversion.
