abstract = {We present a novel route for the preparation of supported
IrO2 catalysts for the oxygen evolution reaction in proton
exchange membrane electrolyzers. It uses carbon soot as a
nanostructure template, which is sequentially coated with a
conductive niobium-doped titanium oxide (NTO) layer and an
ultrathin, highly pure IrO2 catalyst layer by atomic layer
deposition (ALD). The NTO acts as an oxidation-stable
conductor between the metal current distributor and the
catalyst. The highly controlled film growth by ALD enables
the fabrication of electrodes with a very low noble metal
loading. Nonetheless, these electrodes exhibit very high
catalytic activity and good stability under cyclic and
constant load conditions. At an IrO2 content of less than 10
percent by mass of the oxide material and an area-based Ir
content of 153 μg cm−2, the nanostructured NTO/IrO2
electrode achieves an oxygen evolution current density of 1
mA cm−2 at an overpotential of ≈250 mV, which is
significantly lower than the reported values for particulate
NTO/IrO2catalysts.},
