In response to the increasing availability of hydrogen energy and renewable sources, molybdenum disulfide (MoS2)-based electrocatalysts are becoming increasingly important for efficient electrochemical water splitting. This study involves incorporation palladium nanoparticles (PdNPs) into hydrothermally grown MoS2via a UV light assisted process afford PdNPs@MoS2 as an alternative electrocatalyst storage conversion. Various analytical techniques, including scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS), dispersive (EDS), were used investigate morphology, crystal quality, chemical composition samples. Although PdNPs did not alter MoS2 oxygen evolution reaction (OER) activity was driven at considerable overpotential. When splitting performed in 1.0 M KOH aqueous solution with (sample-2), overpotential 253 mV observed. Furthermore, OER performance highly favorable through rapid kinetics low Tafel slope 59 dec-1, well high durability stability. accordance results, sample-2 showed also lower charge transfer resistance, which again provided evidence activity. The enhanced attributed number factors, structural, surface compositions, synergistic effects between PdNPs.
