Abstract: High-entropy metallic glass nanoparticles (HEMG-NPs) have emerged as promising catalysts for oxygen evolution reaction (OER), owing to their abundant low-coordination active sites and exceptionally large specific surface area. However, the practical application of HEMG-NPs has been hindered by the scarcity of reliable synthetic methods and insufficient understanding of their structure-property relationships. Here, we developed a novel synthesis strategy for Ni-Co-Mo-P-B HEMG-NPs by integrating laser evaporation and inert gas condensation technique (Laser-IGC), coupled with rational compositional design. Our investigations revealed that increasing the content of high-valence molybdenum (Mo) not only promotes progressive amorphization of the material but also significantly modulates its electronic structure. Remarkably, the (NiCo) 65 Mo 10 P 25 B 5 HEMG-NPs demonstrated superior OER performance, achieving an overpotential of merely 267 mV at a current density of 10 mA cm−2, which represents a substantial improvement over their crystalline counterparts. Our findings provide profound insights into the structure-property correlations within HEMG systems and establish a universal and effective approach for enhancing the electrocatalysis activity of HEMG-NPs. [Display omitted] • Novel Ni-Co-Mo-P-B HEMG-NPs were successfully synthesized by the laser-IGC technique. • Comprehensive characterization reveals a progressive amorphization of Ni-Co-Mo-P-B NPs with increasing Mo content. • Structural amorphization and electron transfer lead to improved performance of Ni-Co-Mo-P-B samples. • The (NiCo) 65 Mo 10 P 20 B 5 HEMG-NPs show the best OER performance, with a low overpotential of 267 mV at 10 mA cm−2.
