Bifunctional Electrode Design Targeting Co‐Enhanced Kinetics and Mass Transport for Hydrogen and Water Oxidation Reactions (Adv. Funct. Mater. 40/2023)

Bifunctional Electrode Design In article number 2302586, Yeon Sik Jung, Hyun S. Park, and co-workers show that cross-stacked Ir and Pt nanowires resolves the bottlenecks of two reactions essential for the hydrogen-based energy system: (i) hydrogen spillover phenomenon between Pt and Ir nanowires to expedite the hydrogen oxidation reaction and (ii) spacing Ir nanowires sufficiently to enhance the mass transport of the oxygen evolution reaction for polymer electrolyte membrane unitized regenerative fuel cells.
