Nowadays, the assembling of hybrid water electrolysis using a hydrazine oxidation reaction (HzOR) instead slow anodic oxygen evolution (OER) has been established as favorable technology for efficient hydrogen (H2) production. Nevertheless, it is still critical to develop highly effective bifunctional electrocatalysts both (HER) and HzOR. In this work, we propose facile approach design synthesis single-Pd-nanoparticles-decorated bimetallic NiCo2O4 nanoplates electrocatalyst HER Initially, are synthesized by combination hydrothermal high-temperature calcination. Subsequently, single-Pd nanoparticles with varying proportions decorated on via pulsed laser irradiation (PLI), leading formation Pd/NiCo2O4 composites. The optimized composite shows remarkable electrocatalytic ability low overpotential 294 mV an ultrasmall working potential −6 (vs RHE) HzOR at 10 mA cm–2 in 1 M KOH electrolyte. Thus, overall splitting (OHzS) electrolyzer Pd/NiCo2O4∥Pd/NiCo2O4 system presents current densities 100 respective cell voltages 0.35 0.94 V. Notably, situ/operando Raman spectroscopy confirms surface α-Co(OH)2 during γ-NiOOH Furthermore, density function theory (DFT) calculations demonstrate that decoration Pd onto facilitates optimization adsorption free energy (ΔGH*) enhancement dehydrogenation kinetics. This work introduces strategy fabricating electrocatalysts, potentially useful energy-saving H2

The present study details the strategic development of Co-doped CuO nanostructures via sophisticated and expedited pulsed laser ablation in liquids (PLAL) technique. Subsequently, these structures are employed as potent electrocatalysts for anodic methanol oxidation reaction (MOR), offering an alternative to sluggish oxygen evolution (OER). Electrochemical assessments indicate that Co-CuO catalyst exhibits exceptional MOR activity, requiring a reduced potential 1.42 V at 10 mA cm
