Catalysts: Toward Full Exposure of 'Active Sites': Nanocarbon Electrocatalyst with Surface Enriched Nitrogen for Superior Oxygen Reduction and Evolution Reactivity (Adv. Funct. Mater. 38/2014).

Carbon nanotubes (CNTs) are selected as the platform to demonstrate the potential of full exposure of “active sites” at the surface by Q. Zhang, D. S. Su, F. Wei, and co‐workers on page 5956. Novel nitrogen‐doped carbon coaxial nanocables with the pristine CNTs as the core and the N‐doped carbon layers as the shell are available. They possess very high electrical conductivity and much enhanced electrocatalytic activity for both oxygen reduction and evolution reaction. [ABSTRACT FROM AUTHOR]
