The distinctive solid-solution construction and multi-element compositions of high-entropy alloy nanoparticles (HEA NPs) have garnered substantial consideration. Varied strategies have been developed to organize a various array of HEA NPs utilizing completely different substrates for help and stabilization. On this research, we current a facile surface-mediated discount methodology to organize HEA NPs (AuAgCuPdPt) embellished germanane (HEA NPs@GeNSs), and make use of X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) to characterize their construction, composition, and morphology. Subsequently, we reveal that the HEA NPs could be liberated from the GeNSs floor as freestanding methods by way of simple publicity to UV gentle. We additionally discover germanium nanoparticles (GeNPs) as a substitute substrate for HEA NP, given their similarity to germanane and their Ge-H floor. Lastly, we prolong our investigation to bulk Ge and reveal profitable deposition of HEA NPs.
