Heteroatom-doped, carbon-supported metal catalysts for electrochemical energy conversions

Heteratom (N, B, S, P)-doped carbon nanomaterials are viable supports for metal nanostructures because of their ability to tune the electronic and geometric properties of carbon. The interaction between heteroatom and metal as well as the high conductivity and surface area of the doped carbon-based materials and are suggested to significantly enhance the catalytic performance of the hybrid structures. In this chapter, the catalytic performance as well as the structural tuning of heteroatom-doped carbon (especially for the N-doped carbon) supported metal catalysts are systematically discussed. Oxygen electrocatalysis, hydrogen electrocatalysis and CO₂ reduction electrocatalysis are introduced. The synthesis-structure-property correlations the catalysts are also revealed.
