Atomically
Isolated Iron Atom Anchored on Carbon Nanotubes
for Oxygen Reduction Reaction
Posted on 2019-10-20 - 19:13
Recently,
electrocatalysts based on anchored dispersive/isolated
single metal atoms on conductive carbon supports have demonstrated
great promise to substitute costly Pt for the oxygen reduction reaction
(ORR) in the field of fuel cells or metal-air batteries. However,
developments of cost-efficient single-atom Fe catalysts with high
activities are still facing various hardships. Here, we developed
a facile way to synthesize isolated iron atoms anchored on the carbon
nanotube (CNT) involving a one-pot pyrrole polymerization on a self-degraded
organic template and a subsequent pyrolysis. The as-obtained electrocatalyst
possessed unique characteristics of abundant nanopores in the wall
of conductive CNTs to host the abundant atomic Fe-Nx active sites, showing ultrahigh ORR activity (half-wave
potential: 0.93 V, kinetic current density: 59.8 mA/cm2 at 0.8 V), better than that of commercial Pt/C (half-wave potential:
0.91 V; kinetic current density: 38.0 mA/cm2 at 0.8 V)
in an alkaline electrolyte. Furthermore, good ORR activity has been
proven in acidic solution with a half-wave-potential of 0.73 V.
