Efficient OER Catalysts: Efficient OER Catalyst with Low Ir Volume Density Obtained by Homogeneous Deposition of Iridium Oxide Nanoparticles on Macroporous Antimony‐Doped Tin Oxide Support (Adv. Funct. Mater. 1/2020)

In article number 1906670, Daniel Böhm, Dina Fattakhova-Rohlfing, and co-workers present a novel scalable approach for the design of a dimensionally stable iridium-based oxygen evolution reaction (OER) catalyst architecture with a very low iridium volumetric loading density but very high OER activity, achieved by conformal deposition of ultrasmall IrO2 nanoparticles on porous microparticles serving as the catalyst support.
