Abstract
The design of a new class of non-noble-metal catalysts with oxygen reduction reaction (ORR) activity superior to that of Pt is extremely important for future fuel cell devices. Here we demonstrate a one-pot, large-scale protocol for the controlled synthesis of new one-dimensional bamboo-like carbon nanotube/Fe(3)C nanoparticle hybrid nanoelectrocatalysts, which are directly prepared by annealing a mixture of PEG-PPG-PEG Pluronic P123, melamine, and Fe(NO(3))(3) at 800 °C in N(2). The resulting hybrid electrocatalysts show very high ORR activity with a half-wave potential of 0.861 V (vs reversible hydrogen electrode) in 0.10 M KOH solution, 49 mV more positive than that of 20 wt% Pt/C catalyst. Furthermore,…
