The Cover Feature shows an oxygen evolution reaction in acidic water splitting using bimetallic Ir‐Fe oxides supported on reduced graphene oxide (rGO). In this Full Paper, J. Lee, I. Kim, and S. Park study effects of physical and chemical properties of the electrocatalysts synthesized using ultrasonic spray pyrolysis on oxygen evolution activity and durability. The results indicate that the unique morphology, narrow particle size distribution, lattice contraction of Ir (oxide), and strong interaction between Ir metal (oxide) and hybrid support of Fe oxides and rGO tuned by post treatments of acid and heat treatments control oxygen evolution kinetics and long‐term stability. More information can be found in the Full Paper by J. Lee, I. Kim, and S. Park on page 2615 in Issue 11, 2019 (DOI: 10.1002/cctc.201900287).
