Electrocatalysis: Controllable Synthesis and Enhanced Electrocatalysis of Iron‐based Catalysts Derived From Electrospun Nanofibers (Small 20/2014)

Porous carbon nanofibers containing iron and nitrogen, represented by the cubes containing the nanofibers in the image, are developed by J. Luo, J. Zhu, and co-workers to efficiently catalyze the oxygen reduction reaction in fuel cells. As described on page 4072, the nanofibers are produced from electrospun polymer fibers that are denoted by the flower-like fiber bundle with an open end in the image. When the oxygen bubbles meet the nanofibers, energies (‘lightning’ from the bubble centers) can be generated.
