Abstract Gold-based (Au) nanostructures are efficient catalysts for CO oxidation, hydrogen evolution (HER), and oxygen (OER) reactions, but stabilizing them on graphene (Gr) is challenging due to weak affinity from delocalized $$p_{z}$$ carbon orbitals. This study investigates forming metal alloys enhance stability catalytic performance of Au-based nanocatalysts. Using ab initio density functional theory, we characterize $${\text {M}_{(n-x)}\text {Au}_{x}}$$ sub-nanoclusters (M = Ni, Pd, Pt, Cu, Ag) with atomicities $$n=1-4$$ , both in gas-phase supported Gr. We find that M atoms act as “anchors,” enhancing binding Gr modulating efficiency. Notably, {Pt}_{(n-x)}\text /Gr shows improved stability, segregation tendencies mitigated upon adsorption The d -band center ( $$\varepsilon _{\text {d}}$$ ) model indicates potential, correlating an optimal range $$-1 \text { }-2$$ eV HER OER catalysts. Incorporating Au into $${\text{M}_n}$$ adjusts closer the Fermi level, especially Group-10 alloys, offering designs efficiency comparable pure Our methodology leveraged SimStack, a workflow framework enabling modeling analysis, reproducibility, accelerating discovery. work demonstrates SimStack’s pivotal role advancing understanding composition-dependent properties Au-alloy clusters, providing systematic approach optimize metal-support interactions applications.

Creating cost-effective, chemically stable electrocatalysts to improve the hydrogen evolution reaction (HER) and oxygen (OER) remains a major challenge in electrocatalytic water splitting. We synthesized highly efficient NiFe-layered double hydroxide (LDH) electrocatalyst using solvent-free method. The formation of well-interconnected metal ions with nanospherical architectures created an extensive electrochemically active surface area enriched catalytically sites, demonstrating synergistic effects. Preserving suitable stoichiometric ratio, such as Ni6Fe4LDH, was crucial enhancing catalytic performance for both HER OER. optimal Ni6Fe4LDH ratio established overpotentials 167 mV (112 dec–1) 280 (116 OER, attaining 10 mA cm–2 current density 1 M KOH. Moreover, demonstrated impressive robustness, up 90 h minor decrease 4.1 4.6% Notably, bifunctional two-electrode arrangement Ni6Fe4LDH/NF||Ni6Fe4LDH/NF, effective electrolysis accomplished, preserving at bias 1.64 V over 140 h, slight loss 3.9% density.
