Ion implantation synthesis of long-term stable high-entropy metallic glass nanoparticles

High-entropy metallic glass nanoparticles (HEMG-NPs) have shown great potential in the development of sustainable energy. Discovering new nanomaterials for electrocatalysis and maintaining their long-term stability is an effective way. The presence of nanoparticles in an independent transparent substrate material provides a unique way for its stability and maximum performance. This special composite structure is very beneficial to the study of the fine structure of a single specific particle. Here, we propose a general synthesis strategy, in which alloy targets are implanted into the substrate by ion implantation and annealed to grow into NPs. The disordered arrangement of ions into the substrate and the subsequent slow dynamics, disordered microscopic microstructure. Calculating the similarity of the depth range of simulated metal ion implantation provides a theoretical basis for the successful formation of HEMG-NPs. Electrocatalytic water splitting shows that CuCoNiFeZn HEMG-NPs is a non-precious single nano-microcatalyst suitable for multifunctional (HER and OER) electrocatalysis, highlighting its application in sustainable energy conversion. The use of ion implantation aims to synthesize HEMG-NPs with long-term stable storage and minimized denaturation. In further research, the formation of fine structure corresponds to the law of electrocatalytic activity. Develop high-efficiency electrocatalytic HEMG-NPs materials based on the original microstructure.
