Summary: A combination of DFT and experiments was used to study the electrocatalytic activity of Ptn clusters on ITO electrodes. The activity was found to increase with increasing Ptn size and was negligible for isolated Pt atoms on ITO. The adsorption of H atoms on Ptn/ITO was found to be about double the Hupd observed for Pt bulk or nanoparticles. The study also revealed the importance of considering multiple metastable structures and their reactions to accurately predict the activity.

Summary: We report the synthesis and characterization of honeycomb layered strontium iridate (SrIr2O6) as an efficient electrocatalyst for the acidic oxygen evolution reaction (OER) with robust structural stability. Unlike most iridate catalysts, SrIr2O6 can maintain its crystalline structure during OER instead of forming an amorphous active phase. The edges of SrIr2O6 demonstrate high catalytic activity for OER following the adsorbate evolution mechanism, while the basal planes are catalytically inert. SrIr2O6 exhibits about 10-fold higher intrinsic activity than the benchmark catalyst IrO(2), with minimal iridium leaching (approximately 0.03%) and long-term catalytic stability for over 300 hours.

Summary: Density functional theory (DFT) is used to predict the behavior of ruthenium-doped nickel cobalt alloy in the alkaline hydrogen evolution reaction (HER). DFT calculation shows that a synergistic effect at the Ru-Ni/Co interface accelerates water dissociation and optimizes the adsorption-desorption energetics toward the H intermediate. However, excessive Ru introduction leads to over-strong hydrogen adsorption on the catalyst surface, limiting H2 release.
