Facile Synthesis of High-Entropy Alloy Nanoparticle Decorated Germanane

High-entropy alloy nanoparticles have attracted substantial research interest because of their multi-elemental compositions, intriguing solid-solution structure, as well as applications (e.g., multifunctional catalysis). Various methods for the synthesis of these materials have been reported. Even so, the vast compositional space and complex structure result in great challenges related to comprehensive investigations and fundamental understanding. Herein, we will outline a new method for preparing high-entropy alloy nanoparticles comprising Au, Ag, Cu, Pd, Pt that are supported on germanane via comparatively mild solution reduction and in-situ growth. The resulting materials were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electron microscopy.
