Abstract
A method is disclosed for producing carbon fibers with active components such as those for oxygen reduction reactions (ORR). The method includes electrospinning a solution of polyacrylonitrile (PAN) and a transition metal into composite fibers; and annealing the composite fibers in an inert/reducing atmosphere.
